Seahawks: Seattle quarterback Matt Hasselbeck will miss at least three weeks because of a strained ligament in his right knee, coach Mike Holmgren confirmed Monday. An MRI showed the Pro Bowl quarterback strained the medial collateral ligament while getting rolled into by a Minnesota pass rusher Sunday. Seneca Wallace, a fourth-year veteran, will make his first NFL start Sunday at Kansas City (3-3). The Seahawks (4-2) are already without league MVP Shaun Alexander, who remains out indefinitely due to a broken foot.

Chargers: Shawne Merriman’s attorney said the Chargers’ outside linebacker failed a drug test because of a tainted supplement and will continue to play while appealing his four-game suspension.

Steelers: The Steelers aren’t saying if quarterback Ben Roethlisberger sustained his second concussion in slightly more than four months. Roethlisberger briefly was knocked unconscious during a helmet-to-helmet hit with the Falcons’ Chauncey Davis.

Broncos: Denver left tackle Matt Lepsis is out for the season after tearing a ligament in his right knee.

Bears: Chicago defensive back Ricky Manning Jr. met with NFL officials last week and said Monday he’d be disappointed if he is suspended for his role in an altercation with a man in a Los Angeles restaurant last spring. Manning pleaded no contest last month to a felony assault charge.

Redskins: Santana Moss has a strained left hamstring, not the only thing ailing the Redskins, who head into their bye week with a lengthy list of injuries.

Titans: Tennessee receiver David Givens had a pin removed from his left thumb Monday, and coach Jeff Fisher said he could play against Houston on Sunday. Givens broke his thumb and tore a ligament against Dallas on Oct. 1, but finished the game.

Saints: For the first time this season, the Saints’ Michael Lewis was back in pads returning kicks – in practice, anyway. But it remains to be seen if the lone New Orleans native among the Saints will play a role in the franchise’s storybook return as fans recover from Hurricane Katrina.
