Sources: Dolphins RB De'Von Achane suffered torn ACL vs. Chiefs - ESPN

Miami Dolphins running back De'Von Achane suffered a torn ACL during Sunday's loss to the Kansas City Chiefs and will be out for the rest of the 2026 season, sources told ESPN's Adam Schefter and NFL Network's Ian Rapoport on Monday.

Achane was injured on his third rushing attempt of the game Sunday, when he was tackled awkwardly by Chiefs safety Alohi Gilman. Achane was slow to leave the field and was eventually escorted to the blue medical tent under his own power. He ultimately left the tent after a few minutes and was taken to the locker room for additional testing before being ruled out in the second half.

After the game, Dolphins coach Jeff Hafley said the team was still gathering information on the injury but admitted that things did not look promising.

«To be very honest with you, it does not sound very optimistic at this moment,» Hafley said. «But I can't give you any other details until I have them.»

Achane had rushed for 127 yards on 34 carries in three games. He was coming off the best season of his career in 2025, when he recorded 1,838 yards from scrimmage and 12 total touchdowns en route to his first Pro Bowl nod.

Behind Achane, Ollie Gordon II was the only other active running back for Sunday's 24-10 loss that dropped the Dolphins to 0-3. Jaylen Wright was inactive with a stinger.

Gordon had 41 rushing yards and a touchdown on 17 carries while also catching three passes for 14 yards.

Wide receiver Malik Washington took snaps at running back after Achane's injury, and Hafley said the game-day roster construction was intentional because of their confidence in Washington's ability to fill in if needed.

Hafley didn't want to speculate on what the Dolphins would do if Achane is forced to miss significant time.
