"We X-rayed it and it appears everything is structurally fine. He might have bruised something or hyperextended something," Sherman said.
Earlier in the game, receiver Donald Driver hurt his left ankle. Reminiscent of last week when Ahman Green went down with what turned out to be a minor knee injury, Driver was down on the turf for several minutes while trainers attended to him and the loss of a starter looked like a real possibility - at least momentarily.
"He was in a position to go back into the ballgame but I held him out," Sherman said.
RB Tony Fisher "tweaked his knee" according to Sherman, but is expected to be fine and could have returned to the game, the coach said.
Packers CB Jason Horton suffered a hip pointer injury late in the game.
