Several have speculated that he has a torn labrum, which would be consistent with the sketchy reports, and the alleged injury video.

Even if he has a torn labrum, we don't know the severity, if they are trying surgical or nonsurgical treatment, etc. Recovery is unpredictable, which is consistent with the statements we are now hearing. Until we know more, the range of possibilities is very wide, and could include being back after Thanksgiving to being done for the year. Current options on the roster are several, although each is a question mark: Ayers, Moore, Easley, Fleming (PS), and Bequette (PS). It will be interesting to see what they do tomorrow, but I would not be surprised if they tried Easley, Moore and Ayers in a limited role right off the bat.
