Top running back Clinton Portis still is experiencing problems five days after suffering a concussion in the Redskins' last game, stirring questions about whether he might sit out the remainder of the season.
"He came in today. He still has a little, I don't know, if it was like a ringing in his head," Zorn said. "He checked in with our trainers. We sent him back home to keep him docile, if you will. We'll get a better evaluation next week."
"I'm not an expert concussions, so I would not begin to even try to speculate on" what the ringing in his head means, Zorn said. "I just know that we just have to be really careful with trying to get a guy back ... These are pretty difficult things to deal with. We're going to try to do the right thing."
