Washington Redskins cornerback Chris Culliver missed his second consecutive practice with a knee injury.
Culliver suffered the injury in practice this week and was scheduled to undergo an MRI for further evaluation.
"It's a concern," Redskins head coach Jay Gruden said Tuesday to ESPN's John Keim. "He relies on his flexibility and speed. It didn't feel right for him throughout the game. He feels he didn't play up to his capabilities and he wants to get it checked out."
