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.--Matt Terelle
