does the / between hamstring and back indicate both tightened up, or was it a guess that it was an either or, the hamstring "or" the back ?? Also, if it was his back, is it normal for a back to tighten on a completely healthy athlete who never had a back injury ? If not, then does that mean he is going to be nursing his back all of 2017, and we won't hear about it till this time next year, just like we have found out recently of players that nursed injuries most of if not all of last season. It would be great if we can get confirmation that it was nothing more than his thigh cramping a bit due to the high heat, that is why I am asking, would hate to see him less than 100% this season. Even if not an official statement, is there any buzz amongst folks connected to the program that would know for sure what the deal is here. Thanks.
