The San Francisco 49ers are signing running back Ameer Abdullah and wide receiver Andy Isabella to the training camp roster on Thursday after they completed tryouts on Wednesday.
Abdullah is expected to provide depth behind star Christian McCaffrey. Isabella, drafted 62nd overall by the Arizona Cardinals in 2019, also can return punts and is expected to work primarily as a slot receiver.
With 2024 leading rusher Jordan Mason gone, the 49ers had Isaac Guerendo, Patrick Taylor and fifth-round rookie Jordan James in the mix at running back during training camp.
Abdullah, 32, rushed for 311 yards with two touchdowns and caught 40 passes for 261 yards with three scores in 16 games (three starts) with the Las Vegas Raiders last season.
He has rushed for 1,994 yards with eight touchdowns and added 203 receptions for 1,468 receiving yards and 11 scores in 141 career games (26 starts) with the Detroit Lions, Minnesota Vikings, Carolina Panthers and Raiders. He was selected by the Lions in the second round of the 2015 NFL Draft.
Isabella, 28, most recently played for the St. Louis Battlehawks (UFL). He spent time on the Pittsburgh Steelers practice squad in 2024 and was last on an NFL roster with the Baltimore Ravens (2022) and Buffalo Bills (2023).
