The Giants have re-signed quarterback Alex Tanney and waived running back Austin Walter, the team announced on Friday.
Prior to Thursday's loss to the Patriots, the Giants -- in desparate need of running back depth without Saquon Barkley and Wayne Gallman -- waived Tanney and elevated Walter from the practice squad. Walter did not get a carry, but did see the field for one snap on Thursday.
Tanney will return to his role as the team's third-string quarterback behind Daniel Jones and Eli Manning. He was inactive for the first five games of the season before his brief release for Thursday's game.
