Arizona Cardinals receiver Larry Fitzgerald suffered a concussion while trying to recover an onside kick Sunday, ESPN's Adam Schefter tweeted.
Cardinals coach Bruce Arians said after the game that Fitzgerald was undergoing standard protocol for head injuries, but added that no further information was available.
Fitzgerald suffered the injury while trying to recover a Tennessee Titans onside kick late in the fourth quarter of the Cardinals' 37-34 overtime win. Fitzgerald initially had the ball before taking a big hit and losing it before Tennessee recovered.
FOX cameras showed a visibly shaken up Fitzgerald on the sidelines immediately after the play, and the receiver headed to the locker room shortly after.
