On a 1st-and-10 play for the Green Bay Packers, linebacker Denzel Perryman was rolled-up on in a weird fashion that caught his knee at an odd angle. He was still on the ground following the play as medical staff ran to assist.
As of now, the injury looked fairly rough and I doubt he returns to the game. We will update this with any further information as it comes.
UPDATE: Perryman was able to walk off the field on his own.
