Arizona Cardinals wide receiver Larry Fitzgerald sustained a concussion attempting to recover an onside kick in the fourth quarter of Sunday's 37-34 overtime win against the Tennessee Titans, multiple media outlets reported Monday.
Fitzgerald missed overtime while going through the league's concussion protocol, according to ESPN NFL Insider Adam Schefter.
Fitzgerald also was evaluated for a concussion last October and suffered one late in the 2010 season. He will have to be cleared to suit up this week against the Seattle Seahawks.
Fitzgerald got hurt when he was hit by Tennessee's Jackie Battle trying to field an onside kick in the fourth quarter. The Titans recovered and tied the game.
Meanwhile, quarterback Carson Palmer suffered a high ankle sprain in Sunday's game.
Palmer came into the game with a right elbow injury that had limited him in practice the last couple of weeks.
Palmer was hit low by Titans defensive end Kamerion Wimbley early in the game, drawing a flag for roughing the passer. Palmer had his left ankle taped but never came out of the game.
Palmer completed 20 of 30 passes for 231 yards and a touchdown and didn't throw an interception for the fourth time in the last five games.
