INDIANAPOLIS -- The Indianapolis Colts continued to add depth to their offensive line.

Guard/tackle Joe Reitz signed his one-year, $1.43 million qualifying offer as a restricted agent Thursday. Reitz, who went to high school in the Indianapolis area, has started 20 of the 34 games he's appeared in during his career. The Colts claimed Reitz off waivers from the Miami Dolphins in 2010.

The problem with the 6-7, 323-pound Reitz is his inability to remain healthy. He missed two games with a concussion last season and seven in 2012 with concussion and knee problems.

With Jeff Linkenbach signing with Kansas City, Reitz has an opportunity to be the Colts' primary utility backup offensive line because he plays either the guard or tackle position.
