Cardinals' L.J. Collier: Dealing with knee injury

Collier is questionable to return to Sunday's game against Carolina due to a knee injury, Theo Mackie of The Arizona Republic reports.

Collier likely picked up the injury during the first quarter of Sunday's game, and he'll undergo more testing to determine the severity of the issue. PJ Mustipher is in line to see an uptick in snaps at defensive tackle for as long as Collier is sidelined.
