PITTSFORD -- One day after Buffalo Bills General Manager Doug Whaley said he probably wouldn't fill any of their roster openings before the start of training camp, the Bills have added a pair of offensive linemen.
Interior lineman Antoine Caldwell and tackle Tony Hills are on the team.
The Houston Texans drafted Caldwell in the third round in 2009. He was a spot starter for them at center and guard for four seasons.
The Pittsburgh Steelers drafted Hills in the fourth round in 2008. He has played eight NFL games for the Steelers, Denver Broncos and Indianapolis Colts. He made his lone start last year.
