It was his clavicle on that low hit when he lowered his head. I remember the play as I was talking to Alyo...and said I think Brown just busted his clavicle on that hit....then, a few minutes later they said he was out! If you seee the play...it's clear when it happened. iirc
Anyway, his wheels are fine...it was an upper body injury and tho i don't mean to be so glib about injuries...anything NOT lower body for a RB is great!!!
It's like a QB that breaks his left hand when he's a right hander...it's no big deal and one can play with that. imo
