Purely anecdotal I know but I pulled my hamstring about 8 months ago pretty bad. It wasn’t so bad that it hurt when I walked, but I couldn’t run or even jog without a good deal of discomfort. I rested it, stretched it, iced it, jumped in the cold plunge machine quite a few times and let it heal. I ran 5 miles this morning and the damn thing still hurts. Hammies can be tricky. Now I’m 48 and Teemer is in his 20’s, but how he looked Saturday night, he won’t be able to push himself in practice for quite a bit. Time off the mat would obviously affect his conditioning, timing etc. I wouldn’t expect him back for a few months. Hopefully it’s a lot milder than it looked, but he was having a hard time walking off the mat.
