The Bills have signed a couple of free agents, one of whom was a part of their offseason training program a year ago.

Thursday, the team announced that QB Aaron Corp and OL Hutch Eckerson have signed contracts. In accordance with team policy, terms of the deals were not disclosed.

Corp re-joins the Bills after a stint with the team in May as an undrafted free agent. The 6-3, 205-pound Richmond product threw for 2,682 yards and 17 touchdowns in 11 games in 2011. He began his collegiate career at USC (2008-09) before transferring to Richmond (2010-11).
