The NFL and NFL Players Association have begun an inquiry into the on-field machinations of New England Patriots wide receiver DeVante Parker's head injury sustained in Monday night's game, ESPN and NFL Network reported.
Specifically, the league and union are reviewing why the game wasn't stopped despite Parker wobbling after a hard hit in the first quarter. Instead, it was Parker's teammate Nelson Agholor who beckoned game officials to stop play and get Parker off the field.
Parker was subsequently removed from the game when the Arizona Cardinals challenged his catch on the play in question. He was then ruled out for the rest of the game.
