Who Should I Start? Mike Boone or Michael Carter

Free-agent running backs Mike Boone and Aaron Shampklin have signed contracts with the Miami Dolphins. The Dolphins wasted little time beefing up their running-back corps after they lost Alexander Mattison (neck) to a season-ending neck injury following their first preseason game on Sunday. Boone played in six games for the Carolina Panthers in 2024, handling 13 carries for 51 yards. Shampklin appeared in four games for the Pittsburgh Steelers last season, carrying the ball six times for 17 yards. Both players will compete with Ollie Gordon II and Jaylen Wright for a reserve role behind locked-in starter De'Von Achane.

The Arizona Cardinals announced on Tuesday that they re-signed running back Michael Carter to their practice squad and released running back D'Ernest Johnson in a corresponding move. The move to add Carter back to the team was made after they released him on Monday. Coming out of their Week 8 bye, the Cardinals currently only have Bam Knight and Emari Demercado (ankle) on the active 53-man roster at the RB position, so if Demercado cannot play in Week 9 against the Dallas Cowboys, Carter will most likely rejoin the active roster this weekend. The 26-year-old was Arizona's lead back for the first game after Trey Benson (knee) landed in Injured Reserve, but Knight took over lead-back duties the following week and hasn't looked back. Carter is only averaging 2.8 yards on the ground on 35 rushing attempts in his four games in 2025 with the Cardinals and is only a bench stash for RB depth in deeper fantasy leagues.
