Rapoport: Derek Carr avoided serious injury but could miss time; Carr has AC joint sprain (Sports Med Dr Jesse Morse predicts 1 - 4 wks)

I'll be pleasantly surprised if it's a 1-2 week injury. I played with it after two weeks but wore a restrictive brace and it wasn't all the way right for more than a month. And that was on my off shoulder as a position player. I can't imagine a pro QB like Carr, even with the best treatment, will be loading his throwing shoulder and throwing full tilt in two weeks. Hope I'm wrong, but that would be miraculous...
Yea, sure seems like 3-4 weeks will be the earliest he returns.
