Running back Clinton Portis might sit out next week's road game against the Oakland Raiders because of lingering affects from a concussion.
On Monday, Portis will travel to Pittsburgh to be examined again by concussion specialists at the University of Pittsburgh Medical Center, Coach Jim Zorn said after practice today at Redskins Park. After the two-day evaluation, Portis is scheduled to return to Redskins Park on Wednesday.
It seems highly unlikely that Portis, who as of this week still was experiencing dizziness during workouts, would play in the game at Oakland.
"He still has a little bit of dizziness or just not feeling right," Zorn said.
But Zorn would not rule out Portis, who has missed three straight games after suffering the concussion in the Week 9 loss to the Atlanta Falcons and will not play in Sunday's game against the New Orleans Saints at FedEx Field.
