Washington Redskins RB Clinton Portis is still feeling the aftereffects from his concussion, which the Washington Post reports is “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,” coach Jim Zorn explained. According to the Post, Portis is a good bet to sit out another few games “at the very least.” Ladell Betts will be the starter while Portis recovers from the concussion.

Elsewhere around the NFL:

Miami:  Dolphins LB Joey Porter will not play against the Bucs Sunday because he has been benched by head coach Tony Sparano. Nobody is certain what happened, but the Dolphins are saying the outside linebacker won’t play because of a “coach’s decision.” Matt Roth and Charlie Anderson are likely to replace Porter in the starting lineup, with Cameron Wake’s role also increasing.

Philadelphia:  Eagles running back Brian Westbrook will be back on the field Sunday against the San Diego Chargers after missing two games because of a concussion. Westbrook, who also has been bothered by a sore ankle, practiced twice this week. He deemed himself ready to go Friday before the team left for its flight to California. “I’m feeling a lot better,” Westbrook said. “I’m ready to go.”

Indianapolis:  Colts RB Donald Brown completed a full week of practice Friday and is not on the Colts’ injury report for Week 10. Brown should immediately split carries with incumbent starter Joseph Addai.

Kansas City:  Chiefs coach Todd Haley refused to commit to a starting running back for Week 10 in his Friday press conference. “Either (Dantrell) Savage, (Kolby) Smith, or (Jamaal) Charles,” Haley said. “Depends what play we decide to open with probably.” Haley did guard that by saying Smith still isn’t fully recovered from offseason knee surgery, but the Chiefs clearly plan to keep their three-headed RB “monster” intact. Despite a favorable matchup with Oakland, one of the Chiefs RBs are not a strong fantasy options because there is not telling who will get the carries.

Atlanta:  Falcons WR Michael Jenkins was a late addition to the Atlanta Falcons’ injury report with an illness. Brian Finneran is also a question mark for Sunday’s game against the Panthers.

New England:  The Patriots downgraded Sammy Morris (knee) to “out” for Sunday’s game against the Colts.
Morris, who was not a good fantasy option, returned to a limited practice on Friday, meaning there’s a good chance he could go in Week 11. Laurence

San Francisco:  ESPN’s Len Pasquarelli is reporting that if 49ers CB Nate Clements is back with the 49ers next season, it will “almost certainly” be as a safety. His bloated contract that runs through 2013 will make it tough for the Niners to bring him back as a safety. Tarell Brown and Shawntae Spencer will probably be the team’s starting corners in 2010.
