I've had a hammy pull, and while I've never been in AR's physical shape in my entire lifetime, it does take time for a hammy to recover. I was very sore for over a month, and it was 10-12 weeks before I felt close to back to normal. I could still walk around and do normal stuff, but I couldn't do anything athletic that would put a strain on it or it felt like I was being stabbed with a dull butcher knife. A groin pull is just as nasty in my experience. In my early 40's, I finally figured out that I wasn't in my 20's any longer....
Let's all hope that it's not a bad sprain and that he recovers quickly.
I don't think that Dan or any of the staff would risk AR's season health, just to have him play vs UA.

The hamstrings are a collection of three muscles located in the back of the thigh that are responsible for bending, or flexing, the knee.
A grade 1 strain describes fibers that are stretched but not torn.
A grade 2 strain occurs if there is a partial tear of some of the muscle or tendon fibers.
A grade 3 strain describes the rare situation where there is complete tear or rupture of the muscle or tendon.
There can be worsening of the severity of a hamstring pull if strenuous activity is attempted before the muscle has fully healed.
