The San Diego Chargers placed linebacker Antwan Barnes on injured reserve Wednesday.
Barnes, who is dealing with a hamstring injury, had nine tackles and three sacks in 11 games for the Chargers this season.
San Diego also signed veteran guard/tackle Reggie Wells. The Clarion product spent the first seven years of his career with the Cardinals before being traded to Philadelphia in 2010. After spending one year with the Eagles, Wells played for the Panthers in 2011.
