A couple of points: I never had injuries to my hands, but when my orthopaedist asked what on earth I'd done to them, it occurred to me (a month later) that I was a catcher (left hand) and threw the javelin(right hand).
Also, Gabby was slowed down and (IIRC, once sidelined) with the hip flexor issue last year. Chong three years ago with the ITB issue. I've had both of these, and while they may not be debilitating, they can certainly slow one down, and neither can be surgically repaired.
Plus, as has been said, we really don't know the entirety of Camara's issue. An MCL sprain can have a long recovery time, though, and easing in for 5-10 minutes a game a couple months after incurring it doesn't seem unreasonable for me, especially for someone with tender knees.
