The Chargers look to be bolstering their offensive line depth ahead of the draft.
Via his verified Twitter account, free agent offensive tackle Chris Hairston indicated Wednesday he was joining the Chargers, making the announcement in an Instagram post. The 26-year-old Hairston had spent the last four seasons with the Bills, who did not tender him a contract offer in restricted free agency.
Hairston (6-6, 330) appeared in 41 regular season games for the Bills, making 12 starts, with starts at both left and right tackle. He played 16 games as a reserve in 2014.
A fourth-round pick in 2011, Hairston is likely to compete for a reserve role with the Chargers, who have King Dunlap at left tackle and D.J. Fluker at right tackle.
