Gabe Carimi placed on injured reserve

LAKE FOREST, Ill. -- The Chicago Bears placed rookie right tackle Gabe Carimi on injured reserve, officially ending his season.

Carimi, the Bears' first-round draft choice out of Wisconsin, started the first two games of the season at right tackle, but has been out since he suffered a partially dislocated right kneecap in Week 2. He attempted to return to practice following the Bears' bye week, but was shut down after the workout when he continued to experience pain in the knee. He underwent a scope to clean out debris Nov. 11.

"[We're] disappointed, yes, but he's been out for while and we've played most of the season without him," Bears coach Lovie Smith said. "Gabe eventually will be a great player for us. But right now, other guys have stepped up and we've moved on."

Smith was unsure when Carimi would be able to resume football-related activities.

"He's on injured reserve now so we have a little bit of time," Smith said. "Those things will take care of itself."

The Bears promoted offensive tackle Levi Horn from the practice squad to fill Carimi's spot on the active roster.

Horn spent the majority of the past two seasons on the Bears' practice squad after he entered the league in 2010 as an undrafted free agent out of Montana. Horn was a four-year starter at Montana and helped lead the Grizzlies to a 14-1 record his senior year.

Horn is the second practice squad offensive lineman to be elevated this week after Rick Henry took the roster spot of starting left guard Chris Williams, who was also placed on injured reserve earlier in the week.
