[Redskins] Redskins To Be Cautious With RB Clinton Portis

Redskins running back Clinton Portis was knocked out of Sunday's 31-17 loss to the Atlanta Falcons in the second quarter, suffering an apparent concussion on a run that was later called back because of a holding call. "You tell me what happened," Portis said after the game. "I don't remember what happened." Head coach Jim Zorn said it was too early to say how long Portis might be out, if at all. "He had kind of one of those smiles on his face that you know [he] was wondering what the heck happened," Zorn said. "I would never make a diagnosis on a guy getting knocked out. We just have to wait and see. There'll be some tests to see whether or not there was a concussion and how long it takes." Zorn said the team would be "cautious" about Portis's return.
