ASHBURN, Va. (AP) - Clinton Portis is again "very doubtful" for the Washington Redskins as he continues to recover from a concussion.
Coach Jim Zorn said Wednesday that the running back is still experiencing blurry vision resulting from a helmet-to-helmet hit 10 days earlier at Atlanta.
Portis attended a team meeting in the morning before seeing a doctor for more tests.
Zorn says Portis needs to be symptom-free for 24 hours, then get medical clearance and go through a practice before playing. That timetable leaves little chance that Portis will play Sunday against Dallas.
Ladell Betts rushed for 114 yards subbing for Portis in a 31-17 win over Denver.
Zorn also said defensive tackle Albert Haynesworth will be a "weekend decision" with a sprained ankle.
