San Francisco 49ers safety Donte Whitner has departed the game with a knee injury. He was replaced briefly by C.J. Spillman, returned and then left again before being ruled out by the 49ers. According to the media on hand, the injury did not appear to be too serious. Whitner was seen sitting on the bench with ice on his knee. We don't know exactly what it means, but it's certainly better than seeing him go to the locker room to get checked out.
