The Miami Dolphins made the roster move official Monday, September 28: running back De’Von Achane is headed to injured reserve. The team’s announcement did not identify a diagnosis or timetable. NFL.com, citing reporting by NFL Network Insiders Ian Rapoport and Tom Pelissero, reported that Achane tore his ACL and will miss the rest of the 2026 season.
That distinction matters. Miami has confirmed the injured-reserve transaction; the specific ACL diagnosis and season-ending projection come from league reporting. Lost in Miami is not independently diagnosing an athlete or expanding beyond what those sources say.
The loss changes the shape of Miami’s offense. The Dolphins’ own roster release says Achane has 3,184 rushing yards on 578 carries across 47 career games, an average of 5.5 yards per attempt, plus 1,326 receiving yards and 13 receiving touchdowns. He was a 2025 Pro Bowl selection and entered this season as a team captain. Those numbers describe a player who affects a defense before the ball is even snapped: his speed can stretch pursuit angles, while his receiving work keeps him involved beyond conventional handoffs.
Miami announced the move one day after its 24–10 loss to Kansas City, when Achane left the game. The next question is not whether one replacement can reproduce everything he does. It is how the Dolphins divide the work—early downs, pass protection, receiving routes and red-zone touches—without asking one player to imitate an unusually explosive skill set.
The official transaction also included Miami waiving defensive lineman Keith Cooper Jr. and releasing edge rusher Clelin Ferrell and defensive lineman Jordan Miller from the practice squad. Those moves add to a week in which the club’s depth chart will need careful watching.
For fans, the cleanest information will come from the team’s injury reports, roster page and press conferences. Social posts can race ahead of official details, especially around surgery and recovery. No return date should be assumed before the player and club provide one.
The league’s injured-reserve rules create roster room, but they do not make the production gap disappear. Coaches still have to decide whether the answer is already on the roster or requires an outside addition.
The bigger football story is immediate: Miami now has to redesign a meaningful part of its offense while the season is moving. Achane’s health comes first. The Dolphins’ response—personnel, play calling and roster additions—will show how much flexibility the offense has without one of its fastest and most productive players.
