I think he got sandwiched between a couple of guys and it took a toll. Looked like he was ready to play through it but either Dobbs or some of the other guys noticed he wasn't quite there...so they sent him in to be looked at. My guess is both arm/shoulder that he was willing to play through, but he also had concussed symptoms that is going to hold him out for a minute....that's what it looked like to my drunk ass anyway.
Soft
Again...
Jalen took a helmet to his jaw, and got rocked. He had trouble seeing before the beginning of the next play and called to the sidelines to be substituted. After he was removed from the game, he did not pass their "concussion screening" (whatever that is), and they would not let him return.
He also had a cut on his forearm that they were addressing on the sidelines, but it was very insignificant.
