Portis ruled out

Clinton Portis will miss a second straight game for the Redskins on Sunday because of the after-effects of the concussion he suffered on Nov. 8 against the Atlanta Falcons.

Coach Jim Zorn said that Portis "is just foggy enough" for him not to let the Pro Bowl running back practice, let alone face the NFC East-leading Dallas Cowboys. "I want to see him practice and I want to see him have those days where when he practices, he doesn't have residual problems," Zorn said. "And right now, he can't even practice so we'll keep him out this week."

Portis had started 40 straight games before last week. Washington is 4-6 in the 10 games that Portis has missed during his six seasons with the Redskins. Ladell Betts will replace Portis as was true during each of the previous 10 games.

Defensive tackle Albert Haynesworth's sprained left ankle, suffered in last Sunday's 27-17 victory over the Denver Broncos, was still in a walking boot on Thursday. Zorn doesn't expect to know if Haynesworth can play until Sunday.

"Albert is coming along," Zorn said. "The swelling is starting to go down. I do believe that will be a game-time [decision]."

If Haynesworth misses his first game since signing with the Redskins in February, Kedric Golston, a regular in 2006 and 2008, would make his second start of the year. Golston started Week 4 against Tampa Bay in place of Cornelius Griffin (elbow).

Backup tackle Mike Williams, who injured an ankle at Atlanta, was on the field but didn't participate in team drills. He'll also be a game-time decision.
