In addition to Abanikanda, the 49ers have signed running back Ke’Shawn Vaughn to the practice squad. He joins Patrick Taylor Jr. on the practice squad as the 49ers continue to add depth to the running back room. Vaughn, 27, has appeared in 43 career games in the NFL, all with the Tampa Bay Buccaneers.
