Alexander told ESPN's Rachel Nichols that he isn't fully recovered from a left knee injury and doesn't expect to play against San Francisco. The former league MVP also has dealt with a broken left wrist and sprained left ankle this season.
Alexander has just 139 yards over his last four games. His total of 492 yards in eight games this season, the last seven of which he's played with a cast over his left wrist, is his lowest eight-game
rushing total since 2000 when he was a rookie backing up Ricky
Watters. His two touchdowns are 26 fewer than he had while leading
Seattle into the Super Bowl two seasons ago.
As for Branch, Seahawks coach Mike Holmgren said on his Seattle TV show Sunday evening that the receiver playing "doesn't seem like the way to go."
Branch, who during practice last week kept saying he was "day-to-day," would miss a third consecutive game because of an injured foot.
