Briggs, Pace listed as doubtful

CHICAGO -- Pro Bowl linebacker Lance Briggs is doubtful for the Chicago Bears' game against the St. Louis Rams, and left tackle Orlando Pace likely won't play against his former team Sunday.

Both players were injured in last week's 36-10 loss to Minnesota.

Losing Briggs (sprained left knee) would be another big blow for a team that is 4-7 after dropping four straight and six of seven. He leads the Bears with 108 tackles and is just about the only bright spot for a defense that gave up 537 yards to the Vikings.

Pace (strained groin) hasn't played to the level that carried him to seven Pro Bowls in 12 seasons with the Rams after signing a three-year contract with the Bears.

Tight end Desmond Clark (neck), defensive tackle Tommie Harris (knee) and cornerback Charles Tillman (mild concussion) are questionable.
