NASHVILLE, Tenn. -- Arizona wide receiver Larry Fitzgerald missed overtime in the Cardinals' 37-34 win while going through the league's concussion protocol after a hit toward the end of regulation. A league source told ESPN NFL Insider Adam Schefter that Fitzgerald did indeed suffer a concussion.

Fitzgerald was hurt during an onside kick with 52 seconds left in the fourth quarter. Fitzgerald, on the field as part of the Cardinals' hands team, got a hold of Rob Bironas' kick in midair and was hit by Tennessee's Jackie Battle, in what appeared to be a helmet-to-helmet collision.
