I still suspect more than just a subscapularis "strain." MRI examination is widely accepted as the imaging modality of choice to detect of rotator cuff tears. However, just like ultrasonography, the detection rate of subscapularis tendon tear is much lower. In coronal images, the subscapularis tendon and muscle lie in the same anatomic plane, so subtle partial tears or even complete tears are difficult to assess and many times underestimated or missed. Most subscapularis injuries/tears are at the tendon (upper), not in the muscle. And MRI images can only detect upper third tears in 50% of cases.
Rest is the most important phase of rehab/recovery. Repetitive activities involving overhead arm movements, such as throwing, lifting, or reaching, can easily stress and restress the subscapularis tendon. They are trying to get Watson back to play as soon as possible. Now that he has sustained additional injury to the subscapularis tendon, rehab should essentially start over from the beginning.
That is unlikely to happen and history is likely to repeat itself.
Six weeks is what I would have recommended before return to practice. Watson returned in 3 weeks. The team or Watson is certainly not going to start from scratch now.
Watson was right when he said he didn't think his shoulder would be right this season. This is probably an astute observation, especially in light that he is likely to enjoy more hits to his shoulder and/or arm when he does return.
