SAN DIEGO (AP) -- The Chargers have signed their top unrestricted free agent, inside linebacker Donald Butler, to a new contract.
Terms of Friday's signing weren't announced.
Butler says staying in San Diego was his goal. He was a third-round draft pick in 2010.
Butler ranked second on the team with 99 tackles last season despite missing three games with a groin injury. He also had a huge play in a wild-card playoff win at Cincinnati, forcing a fumble late in the second quarter after the Bengals had driven inside the San Diego 5.
Butler missed his rookie season with an Achilles injury but came back to start all 16 games in 2011 and record 102 tackles. He has 5½ sacks and three interceptions.
