Shoulder dislocation is a significant injury for rugby players.
Rugby exposes the shoulder to something that is difficult to reproduce in a gym: high forces, repeated collisions, unpredictable body positions, fatigue and contact that you don't completely control.
If you've dislocated your shoulder playing rugby, the important question isn't simply:
"How many weeks until I can play again?"
A better question is:
"Is my shoulder ready for the demands of rugby?"
That distinction matters.
You may have regained movement. You may be strong in the gym. You may even feel comfortable running, passing and completing non-contact training.
But none of those things necessarily means you're ready to put your shoulder back into a tackle.
For return to rugby, I think we need to consider four things:
CONTROL • CAPACITY • CONFIDENCE • DEMAND
And in rugby, Demand is substantial.
Why are shoulder dislocations a problem in rugby?
Rugby combines repeated high-speed contact with situations where the arm and shoulder can be forced into vulnerable positions.
A shoulder dislocation can occur when a player:
- makes a tackle
- is tackled
- lands awkwardly on the arm or shoulder
- experiences direct impact to the shoulder
- has the arm forced into a vulnerable position during contact
- competes at a ruck, maul or breakdown
- falls with the arm extended
Importantly, it isn't only the player being tackled who is vulnerable.
The tackler is frequently exposed to large shoulder forces.
Research examining active shoulder tackles in rugby has reported shoulder forces approaching around two times body weight or more.
That is very different from completing a controlled resistance exercise in a rehabilitation room.
It helps explain why returning successfully to rugby requires more than simply restoring strength.
What should I do immediately after a shoulder dislocation?
A suspected shoulder dislocation requires medical assessment and reduction by an appropriately qualified healthcare professional.
Do not try to force the shoulder back into place yourself.
Imaging is usually required following the injury to confirm the joint has been reduced and to identify associated injury.
A sling is commonly used initially for comfort and protection. How long it is required varies according to pain, associated injury and the advice of your treating healthcare team.
The important point is that this early period is the beginning of rehabilitation, not simply a period of waiting.

What is the risk of dislocating my shoulder again?
This is particularly relevant to rugby.
Younger age is consistently associated with greater recurrence risk after a first-time traumatic anterior shoulder dislocation.
Recent UK research from Makaram and colleagues followed 1,293 people aged 15–35 after a primary traumatic anterior shoulder dislocation.
Overall, 62.8% experienced recurrent instability during follow-up, and participation in contact sport was independently associated with greater recurrence risk.
But recurrence risk isn't identical for every rugby player. Age, sex, injury characteristics and other individual factors matter.
This is why I don't think the conversation should simply be: "You play rugby, therefore you'll dislocate again."
We can estimate risk. We cannot predict an individual player's future with certainty.
My PhD research investigated exactly this problem and led to development of the Predict Recurrent Instability of the Shoulder — PRIS — tool.
Want to understand your recurrence risk?
PRIS was developed from my PhD research following people after a first-time traumatic anterior shoulder dislocation.
It helps estimate risk — it does not tell you whether you should have surgery.
Use the PRIS prediction tool →Return to rugby: beyond the clock
This is an area that Edel Fanning and I have written about specifically in relation to contact and collision athletes.
Return-to-sport decisions after shoulder stabilisation are still often based heavily on time — commonly around four to six months after surgery.
But time alone cannot tell us whether an athlete is ready for contact sport.
Rugby players need to recover physically, but they also need to demonstrate that the shoulder can perform under the demands of rugby and that they are psychologically ready to return.
This is why I prefer to think about return to rugby using:
CONTROL • CAPACITY • CONFIDENCE • DEMAND
CONTROL
Can you control your shoulder when movement doesn't go exactly to plan?
Early rehabilitation usually includes restoring movement and rebuilding shoulder and scapular control.
But rugby eventually requires much more.
The shoulder needs to respond when force is rapid, unexpected, coming from different directions, applied while the rest of the body is moving, and applied while attention is focused somewhere else.
Control therefore needs to progress from predictable rehabilitation exercises towards reactive, sport-specific situations.
CAPACITY
Is your shoulder strong enough for rugby — and can it keep producing force repeatedly?
Strength is important. But there is a problem with relying on one strength test.
Research by Edel Fanning and colleagues looked at traditional rotational shoulder strength alongside more dynamic upper-limb performance tests in contact and collision athletes.
The dynamic tests included: countermovement push-up, press jump, and box-drop landing.
These tests were reliable — but interestingly, performance on them did not correlate closely with traditional isokinetic shoulder strength.
You can measure different things when you test strength and when you test performance.
That is why we don't want to rely on one strength number to decide whether a rugby player is ready.
Strength in vulnerable positions matters
A player may produce good peak rotational strength but still have weakness closer to the end ranges where shoulder instability may occur. This is particularly important in a sport where the arm can be forced into unexpected positions during contact.
Explosive strength matters
Collision athletes don't only need to produce force. They need to produce force quickly. That is relevant during tackling, being tackled, hand-offs, bracing, and falling and absorbing force through the upper limb.
Endurance matters too
One successful tackle is not the same as repeatedly tackling throughout a match. This is why shoulder endurance and fatigue tolerance should form part of the return-to-sport assessment.
Testing the rugby shoulder
There isn't one perfect test that tells us whether a player is ready. Edel and I recommend using a battery of tests that reflects the athlete's injury and the demands of their sport.
This may include assessment of: range of motion, rotational strength, long-lever shoulder strength, explosive upper-limb performance, endurance, proprioception and reactive control, and psychological readiness.
A key principle: Don't rely on a single metric.
The ASH test
The Athletic Shoulder — ASH — test assesses long-lever isometric shoulder strength. One of its advantages for rugby players is that some of the test positions resemble the shoulder position used during tackling.
SARTS testing
The Shoulder Arm Return to Sport — SARTS — test battery was developed to assess shoulder performance in athletes. For rugby players, tests such as line hops, BABER, side-hold rotations and push-up claps can help assess endurance, repeated force production and upper-limb performance.
The tests should match the player and the demands they are returning to.
CONFIDENCE
Do you actually trust your shoulder again?
Our qualitative research into the lived experience of shoulder dislocation found that people became very aware of vulnerable shoulder positions, fatigue and unpredictable movements.
Some participants ultimately changed or stopped contact sport because the perceived threat of another dislocation became greater than their desire to participate. That matters enormously in rugby.
A player may be happy performing heavy gym exercises but still hesitate before putting the affected shoulder into a tackle. That isn't necessarily a strength problem. It may be a confidence problem.
Psychological readiness can be measured
The Shoulder Instability Return to Sport after Injury questionnaire — SIRSI — explores confidence, fear of reinjury, emotional response and belief in the shoulder. It adds an important part of the return-to-sport picture.
DEMAND
What exactly does this player need the shoulder to tolerate?
"Rugby player" isn't specific enough. A winger and a prop don't have identical shoulder demands. Neither do a scrum-half and a flanker.
We need to understand: position, level of play, contact exposure, tackle role, training volume, and match demands.
Then rehabilitation should progressively prepare the shoulder for those demands.
CONTROL + CAPACITY + CONFIDENCE measured against DEMAND.

Returning to contact is a separate stage
Returning to training and returning to contact are not the same decision.
A player may be able to run, pass, kick, complete strength training and participate in non-contact team training without yet being ready to tackle.

RETURN TO COMPETITIVE MATCH PLAY
Each stage asks something different from the shoulder.
How should contact be reintroduced?
Contact shouldn't suddenly appear at the end of rehabilitation. It should be progressively exposed and trained.
1. Prepare for force
Before tackling another player, prepare the shoulder to tolerate force through pushing, pulling, perturbations, landing tasks and controlled loading.
2. Introduce predictable contact
Start with situations where the player knows where the force is coming from, when it is coming, and what movement they are expected to perform. This may include appropriately selected tackle-bag drills and controlled contact.
3. Increase intensity
Gradually increase: FORCE • SPEED • VOLUME
A player who tolerates one controlled tackle hasn't demonstrated the capacity to tolerate repeated contact across a full rugby session.
4. Add variability
Change the direction, approach angle, body position, tackle height, and starting position. Now the task begins to look more like rugby.
5. Add unpredictability
The player should eventually have to react rather than simply rehearse a known movement. Decision making becomes part of the task.
6. Add fatigue
A technically good tackle at the beginning of a session isn't the same as a tackle late in a match. Strength, coordination, reaction time and confidence can all change with fatigue.
7. Full training exposure
Before competition, the player should tolerate the contact demands expected during rugby training. Then ask: How did the shoulder respond during the session — and afterwards?
Build Capacity Before Chaos
Rugby is chaotic. Rehabilitation doesn't need to begin that way.
First develop CONTROL, then sufficient CAPACITY, then progressively rebuild CONFIDENCE, before exposing the player to the full DEMAND of rugby.
Then progressively add: SPEED → CONTACT → VARIABILITY → UNPREDICTABILITY → FATIGUE
Build Capacity Before Chaos. And before returning to the chaos: train the chaos.

How do I know I'm ready to tackle again?
Return-to-contact decisions should use a combination of information, which may include: shoulder range of motion, rotational strength, strength in vulnerable positions, endurance and fatigue tolerance, explosive upper-limb performance, reactive shoulder control, closed-chain capacity, ability to tolerate impact, tackling technique, repeated contact tolerance, psychological readiness, confidence and apprehension, and rugby-specific performance.
The purpose of testing should be to answer: "Is this player prepared for the demands they are returning to?" rather than simply: "Has this shoulder reached 90% of the other side?"
That is why we recommend combining symmetry with absolute performance, sport-specific tests and clinical assessment.

Can a shoulder brace help when returning to rugby?
For some players, yes. But it is important to be clear about what a brace can and cannot do.
A shoulder brace does not make an unstable shoulder stable. It does not replace rehabilitation.
What a shoulder instability brace can potentially do is limit exposure to vulnerable shoulder positions while still allowing the player to move. For some athletes it may also provide external support during the transition back to contact.
This may be particularly useful when progressively reintroducing tackling, falling, ruck and breakdown activity, unpredictable contact and match exposure.
The appropriate brace depends on the direction of instability and the movement that needs to be controlled.

Learn when a shoulder instability brace may form part of a return-to-contact strategy.
Should I wear a brace in training or matches?
If you're planning to use a shoulder brace for rugby, I wouldn't introduce it for the first time on match day.
You need to understand how it feels, how much movement it restricts, whether it affects tackling technique, whether it remains comfortable during repeated contact, whether it stays appropriately positioned, and how it performs when you are fatigued.
The brace should become part of the sporting environment before it becomes part of competition.
Do I need surgery if I want to return to rugby?
Not necessarily. But participation in contact sport is relevant to the decision.
The decision should consider your individual recurrence risk, your imaging and injury, your rugby demands, your position and level of competition, your goals, your tolerance of risk, and the benefits and disadvantages of surgery and rehabilitation.
This should be a shared decision, rather than a decision based on one MRI finding, your age alone or the fact that you play rugby.

Returning to rugby: don't just get strong — get rugby ready
You don't play rugby on a treatment table. You don't tackle at a controlled speed. You don't know exactly where the next force is coming from. And you don't get to stop the match because your shoulder is becoming fatigued.
Returning successfully therefore requires more than healing and more than strength.
CONTROL
Can I control my shoulder when movement becomes fast and unpredictable?
CAPACITY
Can my shoulder produce and repeatedly tolerate the forces rugby requires?
CONFIDENCE
Do I trust my shoulder when I tackle, fall and make contact?
DEMAND
Have I actually prepared my shoulder for my position, level and contact exposure?
CONTROL • CAPACITY • CONFIDENCE • DEMAND
Then close the gap between what your shoulder can currently do and what rugby is going to ask it to do.
