Miami Dolphins star running back De'Von Achane suffered a torn ACL in the Week 3 loss to the Kansas City Chiefs and will miss the rest of the 2026 season, according to ESPN and NFL Media. Achane departed from the 24-10 defeat after less than five minutes of action and was initially deemed questionable to return before the Dolphins downgraded him to out.

Achane sustained the non-contact injury on a first-quarter run. He planted his left leg to cut right, and the leg gave out from underneath him. Achane slowed his run, and a Kansas City defender hit him to complete the tackle.

Early indications from Dolphins coach Jeff Hafley suggested Achane could have suffered a serious injury, and further testing reportedly revealed the torn knee ligament.

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

Following an evaluation in the sideline medical tent, Miami's medical staff escorted Achane into the locker room. He was able to walk under his own power both on his way to the sideline and later to the locker room.

Although he was ruled out for the game, Achane returned to the sideline with his uniform on and, according to CBS sideline reporter Melanie Collins, appeared to be in good spirits.

Achane tallied three carries for 17 yards prior to the injury. That brought his season totals to 34 carries and 117 yards to go with seven receptions and an additional 49 yards through the air. With his campaign now finished, he concluded the year without a touchdown.

Dolphins stretched thin at running back

Ollie Gordon II stepped up a rung on the depth chart with Achane ruled out, and two quarters later he left the game as well. The Dolphins announced that their No. 2 running back reported cramps and was deemed questionable to return.

Gordon was the only other active running back on Miami's Week 2 roster and projects as the top ballcarrier moving forward. He scored the team's first touchdown of the day with a three-yard run in the first quarter.

Gordon, a third-year ball carrier from Oklahoma State, totaled only three touches over the first two weeks of the season but upped that tally to 20 thanks to his increased workload against the Chiefs. He has a modest 90 career carries, which leaves the Dolphins with another inexperienced player handling a sizable role on their offense. The young unit lacks established star power without Achane and could struggle even more to move the ball in the absence of a do-it-all running back.

Without Achane, the Dolphins lost to the Chiefs by two touchdowns. They finished with 119 total rushing yards, led by quarterback Malik Willis, who had 56 yards on the ground off nine carries.
