LAKE FOREST, Ill. -- The Chicago Bears strongly considered elevating Levi Horn in September from the practice squad to the active roster.

Now it appears the club might be closer to actually making that move, according to a source. The reason is depth concerns along the offensive line with left guard Chris Williams out for the rest of the season with a dislocated wrist, and right tackle Gabe Carimi continuing his rehabilitation from arthroscopic knee surgery.

The source expected the Bears to elevate Horn sometime this week, and considered the potential move a technicality at this point.

"I'm ready whenever they want me," Horn said on Wednesday.

Signed as an undrafted rookie by the Bears in 2010, Horn spent the majority of last season on the practice squad.

Should they decline to add personnel to the active roster at the position, the Bears could enter Sunday's matchup against the Chargers with six healthy offensive linemen, which means five starters, and only one reserve. That wouldn't be an ideal situation, and that's why the team spent Tuesday working out players offensive line coach Mike Tice was interested in evaluating at Halas Hall. Jordan Black was standing in dress clothes during practice. Black, who played for Tice in Jacksonville, worked out for the Bears on Wednesday morning.

Tice wasn't available for comment Wednesday coming off the practice field.

Listed in the team's media guide as a tackle, Horn also spent time with the Bears working at guard. Horn played with the second team offense in the preseason, and drew praise from Tice for his vast improvement from Year 1 to Year 2 with the team. Because Horn can play either inside or outside, the Bears could use him as a potential backup at two positions.
