Lance Briggs out at least 6 weeks

LAKE FOREST, Ill. -- The Chicago Bears confirmed Monday that seven-time Pro Bowl linebacker Lance Briggs will miss approximately six weeks due to a small fracture in his left shoulder that will not require surgery.

Briggs suffered the shoulder injury in the second half of Sunday's 45-41 loss to the Washington Redskins. He did not return to the game.

"We're losing a great leader in Lance," Bears head coach Marc Trestman said Monday. "That's going to be tough to overcome, but we have to be confident that we can overcome it."

The Bears will not place Briggs on injured reserve with the designation to return, according to general manager Phil Emery.

"We felt that would be putting us in a box in regards to Lance's recovery time," Emery said. "We are not going to do that."

Briggs performed well against the Redskins before exiting the game and was credited with eight tackles and two pass break-ups.

"I've seen Lance make so many great plays over the years," Bears cornerback Tim Jennings said. "We're going to miss him, but other people are going to have to step up. We all need to dig down deep and raise the level of our play with Lance out. He will always be the leader of this defense."

Trestman said he feels comfortable with either veteran strong-side linebacker James Anderson or rookie middle linebacker Jon Bostic making the defensive calls on the field with Briggs sidelined.

Bostic made his first NFL start in Washington in place of D.J. Williams, who was placed on injured reserve because of a ruptured left pectoral muscle tendon. Blake Costanzo and rookie Khaseem Greene both received playing time in the second half as the Bears' third linebacker.

Briggs has a team-leading 64 tackles and two sacks this season for the Bears (4-3). He recorded at least 100 tackles in eight of his first 10 seasons.
