The Buffalo Bills got on the board first in Jacksonville on Sunday.
But the last offensive play before Matt Prater's field goal was a painful one for Josh Allen.
He was brought down on a run up the middle, and multiple players landed on top of him.
The final defender to hit him appeared to have his backside land hard on the front of Allen's helmet and bend his head a bit.
Allen's helmet came off, and he jogged off the field slowly.

On the sideline, the star QB put his baseball cap on and then headed to the medical tent with trainers.
He appeared to be moving fine, but he likely had to be checked for concussion symptoms.
He did come back out of the tent and appeared fine.
The Jaguars were about to get the ball, so it'd be a minute before Allen would get a chance to get back onto the field.
