The San Diego Chargers have placed outside linebacker Antwan Barnes on injured reserve and re-signed guard-tackle Reggie Wells. Barnes played in 11 of 12 games this season. He had three sacks among six total tackles, including two sacks in a loss to Baltimore on Nov. 25. Wells spent time with the Chargers earlier this season, but did not appear in any games. The Chargers (4-8), who play at Pittsburgh on Sunday, need depth on the offensive line due to injuries. Source: Associated Press
