Redskins running back Clinton Portis traveled to the University of Pittsburgh on Friday to have his concussion checked out. The same doctors evaluated Eagles running back Brian Westbrook. Portis suffered a concussion two weeks ago against the Falcons and hasn't played since. "We're going to make sure we take care of all the details. We're for Clinton getting well," coach Jim Zorn said. "Each day Clinton's done a great job of communicating how he's felt, and that's what it's going to take. "I want to be involved with those conversations, not so much to see 'how fast can we get him back,' but just to make sure the young man is improving and getting better."
