NEW ORLEANS — Reggie Bush has a partially torn left knee ligament that likely won't require surgery but could sideline him for Monday night's game at Atlanta and possibly for the rest of the season.

A person familiar with the injury told The Associated Press that Bush did not expect to play Monday and likely would not risk further aggravating the injury by playing again this season. The person requested anonymity.

Saints coach Sean Payton said Bush would be listed as questionable on the injury report and added whether Bush plays against the Falcons will be a game-time decision.

"We'll monitor where he's at," Payton said after Friday's practice, which Bush sat out. "I'm still hopeful for this weekend's game based on how he practiced yesterday."

Payton said it was "a little premature," to predict Bush would miss the rest of the season.

Bush practiced Thursday and did not indicate he was having any trouble when he spoke to reporters after practice. He became sore that evening, and the team ordered a MRI, which indicated a tear in his posterior cruciate ligament.

Bush had another MRI on Friday.

RAMS' QB UNCERTAIN: Rams quarterback Marc Bulger had a setback in his recovery from a concussion, meaning it's possible Brock Berlin, who has never attempted a pass in a regular-season game, might start Sunday at Cincinnati. Bulger began feeling poorly during meetings Thursday afternoon, said Rams coach Scott Linehan, who added that the decision on a starter is likely to be made late Saturday. Regular backup Gus Frerotte will be the emergency quarterback for the Rams.

MERRIMAN EXPECTS TO PLAY: Chargers coach Norv Turner said it's 50-50 whether All-Pro outside linebacker Shawne Merriman will plays Sunday at Tennessee. The AFC defensive player of the week disagrees. "Yeah, I'll be good," Merriman said Friday after sitting out practice a second straight day to rest his ailing right calf. He injured it Sunday against Kansas City, when he had three sacks to push his season total to 9 1/2. The Chargers (7-5) will need Merriman as they chase mobile Titans quarterback Vince Young. A Chargers win Sunday, coupled with a Denver loss to the Chiefs, will give San Diego consecutive AFC West titles.

COTCHERY DOUBTFUL: Jets wide receiver Jerricho Cotchery was listed as doubtful Friday — but not out — for New York's game against Cleveland with an injured right index finger that kept him on the sideline last week. Cotchery, who reportedly broke the finger in practice last Monday, hasn't been seen in the locker room or on the practice field during media availability since. Laveranues Coles, who played last week against Miami despite a high left ankle sprain, was listed as questionable. He was noticeably hobbled in the locker room and at practice Wednesday by the injury, which occurred early during the Jets' 19-16 overtime win against Pittsburgh on Nov. 18, but appeared to be walking easier later in the week.

STOKELY, WALKER LIKELY: Brandon Stokley and Javon Walker practiced with the Denver Broncos on Friday, and both receivers are expected to play against the Kansas City Chiefs on Sunday. "Both should be able to go if there's no setback," Broncos coach Mike Shanahan said. "We'll just have to wait and see how they are tomorrow."

INDY WANTS SUPER BOWL: Indianapolis will make another bid to host the Super Bowl in the new Lucas Oil Stadium. Despite the excitement generated from the Indianapolis Colts' still-fresh Super Bowl championship, pitches from coach Tony Dungy and Speedway owner Tony George and even a Top 10 list from Indianapolis native David Letterman, NFL owners voted in May to play the 2011 Super Bowl in the Cowboys' new $1 billion stadium in Arlington, Texas. Now, Indy officials have decided to make another try next spring for the 2012 NFL championship.

POLAMALU UNLIKELY: Steelers safety Troy Polamalu is likely to miss Pittsburgh's game Sunday at New England after sitting out practice for the second day in a row Friday because of a sprained knee. Polamalu, who has missed the Steelers' last two games, aggravated the injury during practice Wednesday and has been unable to practice since. He is listed as doubtful, meaning he has a 25 percent chance of playing.

STROUD RETURNS: The Jacksonville Jaguars activated defensive tackle Marcus Stroud on Friday, the final step in his return from a four-game suspension. Stroud rejoined the team Monday and practiced all week in preparation for Sunday's game against Carolina. To make room for Stroud, the Jaguars released linebacker Marquis Cooper.

OUT FOR SEASON: Tennessee Titans safety Chris Hope is out for the season after tests confirmed a spinal cord injury will require rest and possibly surgery but is not expected to be career-ending. "After numerous studies and opinions, Chris Hope's season is over," coach Jeff Fisher said on Friday ... The Houston Texans placed Ahman Green on injured reserve Friday, ending the season for the player signed to be their featured running back. Green missed Houston's last three games with a left knee injury that's bothered him for months. He rushed for 260 yards on 70 carries this season.
