I have no way of knowing but he looked knocked out to me. Offsetting penalties, no ejection, no suspension; why don't they just knock out every starting QB they play.
An uncalled face mask right in front of the ref while Allen was about to escape the rush, Gilmore grabbing John Brown's face as he was about to be wide open over the middle, the flag was thrown and then inexplicably picked up. That game was total bull####. The Bills didn't help themselves by scrambling out of fg range and all the turnovers but NE didn't do anything on offense but got enough help from the Bills and the refs to win. That game sucked.
