The Bears made a couple of moves to their 53 man roster today.

They officially announced 2008 first-round pick, left guard Chris Williams was placed on injured reserve with his wrist injury.

Second-year guard Edwin Williams, who replaced him in the second half played pretty well in his place on Sunday.

He started three games a year ago at right guard and started this training camp at a possible candidate for center.

Head coach Lovie Smith is upset with the injury to Chris Williams, but knows whoever replaces him will have to do well.

Smith won’t announce who is starting this Sunday at left guard against the Chargers, but Edwin Williams should be the likely starter on the left side of the offensive line.

A backup is needed for depth on the offensive line sometime soon.

The Bears would be fortunate if they got rookie tackle Gabe Carimi back from injury.

If that happens, Carimi would go back to right tackle and Lance Louis would likely move back to left guard.

Bears release DE Reed, replace him with veteran DE Davis

Nick Reed appeared in seven games this season making 11 tackles. He was inactive this past Sunday and seemed to fall out of favor after filling in for a banged up Julius Peppers in Week Five.

Reed has talent, he just wasn’t getting it done and the Bears don’t wait for players to make plays. Just look at Mark Anderson last season, no one saw that coming.

The Bears replaced Reed with veteran Chauncey Davis. Davis has appeared in 96 games making 204 tackles, 10 sacks, two interceptions, and two forced fumbles with the Atlanta Falcons.

He was let go by the Falcons this off-season. He signed a two-year deal with the Bears today.

He hasn’t been a sack monster, only recording two sacks in the past two seasons. His best sack total in a season came in 2008, when he had four.

Look for him to practice this week and possibly provide some nice depth at the defensive end position.

The Bears have really only been using three defensive ends on gamedays this season.

Amobi Okoye and Henry Melton are two very athletic defensive tackles, who have been used quite a bit on the outside as well.
