The Buffalo Bills are targeting free agent running back Reggie Bush and are expected to sign him, according to NFL Network's Ian Rapoport:

Buffalo currently will enter the season with LeSean McCoy as the starter and third-year back Mike Gillislee as the backup. Bush would be expected to take over the backup role and help in the return game.
Bush is recovering from a torn ACL he suffered for the San Francisco 49ers in Week 5 last season. He had a hugely reduced role with the 49ers even before the injury, getting just eight carries for 28 yards last season.
