Cleveland Browns' running back Jamal Lewis will sit out Sunday's game against the Miami Dolphins because of a sprained right foot.

Jason Wright is expected to make his fourth career start in Lewis' place.

Lewis hurt the foot on his first carry last week, an 11-yard run in a 34-17 loss to New England. He spent the week in a walking boot and did not practice.

Lewis signed a one-year free agent contract with the Browns in March after spending the past seven seasons with the Baltimore Ravens. He had offseason surgery on his right ankle, but said earlier this week that the foot injury was not related.

Safety Gary Baxter, who is attempting a comeback from a pair of torn patellar tendons suffered last in a game against Denver last year, will also not play against Miami.

Wide receiver Joe Jurevicius, who left the New England game in the second quarter because of a knee injury, remains questionable.

CARR DOWNGRADED: Carolina Panthers quarterback David Carr was downgraded to questionable for Sunday's game against Arizona after his sore back stiffened on the team's cross-country flight.

Carr had been listed as probable after practicing Friday, but he experienced pain on the flight later that night. He was downgraded before the team's afternoon walkthrough Saturday afternoon. Carr is expected to warm up Sunday morning to determine if he'll play.

If he can't go, coach John Fox will have to decide between 43-year-old Vinny Testaverde or undrafted rookie Matt Moore.

Testaverde was signed Wednesday and has been scrambling to learn the offense and his new teammates. Moore was signed last month after being cut by Dallas, and acknowledged he's been a bit overwhelmed working with the first team in practice.

Carr had replaced Jake Delhomme, who will undergo season-ending elbow surgery.

FALCONS WAIVE MALLARD: The Atlanta Falcons waived defensive end Josh Mallard on Saturday and signed linebacker Travis Williams from the practice squad.

Mallard, a three-year veteran from the University of Georgia, had four sacks and 11 tackles in 14 games for Atlanta last season. He made one start last year but did not have a tackle this season.

Williams (6-1, 224) signed with Atlanta as an undrafted free agent last year and re-signed with team on Jan. 10.

Depth at linebacker is a concern for Monday night's game against the New York Giants. Stephen Nicholas is out with an ankle injury and Keith Brooking is questionable with a hamstring injury.

NFL FINES TITANS DE: The NFL has fined Tennessee Titans defensive end Kyle Vanden Bosch $7,500 for a low hit on Atlanta quarterback Joey Harrington.

Vanden Bosch's agent, Anthony Agnone, did not immediately return a call on Saturday from The Associated Press seeking comment.

Vanden Bosch told The Tennessean that he plans to appeal the fine.

"If you watch the play, I beat the tackle and he grabbed my ankle with both hands, so I am falling down and hit him with my arm, not my helmet or my shoulder or anything," Vanden Bosch said. "I don't know how to prevent that. It wasn't a dirty hit. The guy tripped me so I was going down."

The Titans beat the Falcons 20-13 on Oct. 7.

DAVENPORT CHARGED: Pittsburgh Steelers running back Najeh Davenport was charged with domestic violence, child endangering and unlawful restraint in a custody-related confrontation with the mother of his 5-year-old son.

Chief Michael McGrath said Thursday night that Davenport would be given a chance to surrender for a court appearance on the misdemeanors. If convicted, he could face a sentence of 14 months.
