PITTSFORD, N.Y. -- The banged-up Buffalo Bills have signed two undrafted rookie free agents, running back Andre Anderson and receiver Aaron Rhea.

Anderson had 2,009 yards rushing and 17 touchdowns at Tulane. Rhea had 1,811 yards receiving and 19 touchdowns at Stephen F. Austin. Rhea initially signed with Minnesota in April before being released last month.

The Bills also placed linebacker Ryan Manalac on waived/injured.

The moves were announced Monday as the Bills returned to training camp after a 42-17 loss at Washington on Friday to open the pre-season.

Buffalo lost its top two running backs to injury during the game. Fred Jackson is out indefinitely after hurting his left hand, and Marshawn Lynch hurt his ankle.

The Bills host the Indianapolis Colts in an NFL exhibition game in Toronto on Thursday.
