Arizona Cardinals wide receiver Larry Fitzgerald is having a magnetic resonance exam today on his left knee.
Fitzgerald injured his medial collateral ligament late in the first half.
He went back in the game and had a clutch third-down reception in the Cardinals' 14-6 win over the Detroit Lions.
Fitzgerald is expected to continue playing through the injury.
He caught two passes for 33 yards Sunday.
