Rotator cuff muscles are likely to most likely to protect against shoulder dislocation.
Explanation:
The rotator cuff muscles are a group of muscles -infraspinatus, supraspinatus, subscapularis, teres minor. The prime function of these muscles is to stabilize the shoulder joint – glenohumeral joint (a ball and socket joint) and to control its movements. The muscle forms a cuff around the humeral head and rotates the joint.

Any injury or weakness of the rotator cuff muscles will destabilize the shoulder joint and make it prone for dislocations.
