New Orleans Saints cornerback P.J. Williams was knocked unconscious in the scariest injury of the week Sunday against the Giants.

Williams suffered a concussion when in the game's first half he was kneed in the head twice while attempting to tackle Giants tight end Larry Donnell—-once by Donnell himself and a second time by teammate Craig Robinson. According to preliminary reports, he's expected to make a full recovery.

Williams lay on the field motionless after the collision, with players from both teams surrounding him as he was attended to by medical personnel.

The 2015 third-round pick out of Florida State is being evaluated by the league and will follow the NFL's concussion protocol, which could keep him sidelined for a little while.
