De’Von Achane Torn ACL: Dolphins RB Out for Season, Odds Shift Further Against Miami

De’Von Achane’s 2026 season is over. The Miami Dolphins placed their star running back on injured reserve Monday after tests confirmed he suffered a torn ACL in Sunday’s 24-10 loss to the Kansas City Chiefs, a devastating blow that ends any hope of Achane anchoring Miami’s offense for the rest of the year.

Achane went down early, tackled awkwardly by Chiefs safety Alohi Gilman on his third carry of the game. He was slow to get up, eventually made his way to the medical tent under his own power, then was ruled out for the second half after further testing. By Monday, the diagnosis was official: a torn ACL in his right knee, and a season-ending injury for the player Dolphins coach Jeff Hafley called Miami’s “team MVP” a year ago. Achane finished Sunday’s game with just 17 yards on three carries before exiting.

What Achane’s Injury Means for Miami’s Backfield

Achane, who signed a four-year contract extension this offseason, had been Miami’s most explosive offensive weapon and its most reliable source of production behind a shaky offensive line. With him gone, the Dolphins’ running back room is suddenly thin and unproven. Second-year back Ollie Gordon II stepped in Sunday and delivered, rushing for 41 yards and a touchdown on 17 carries, though he was also dealing with cramping issues late in the game. Jaylen Wright, a 2024 fourth-round pick, is the other name in the mix, but he’s been sidelined with a stinger and foot injury and is officially day-to-day, with his availability for Week 4 uncertain. Beyond that duo, Miami’s depth chart drops off to practice-squad options Jarquez Hunter and Carlos Washington Jr., and receiver Malik Washington has already been used as an emergency change-of-pace back.

Hafley confirmed the severity of the injury Monday, saying his “heart breaks” for Achane but that “he’ll be back, and he’ll be back strong.” The coach also said he and general manager Jon-Eric Sullivan will discuss over the next several days whether Miami needs to add a running back from outside the organization, with names like Michael Carter, Dameon Pierce and Miles Sanders among the free agents that have been floated as potential fits. For now, the Dolphins are left piecing together a committee approach behind an offense that has already struggled to move the ball through three weeks.

Betting Market Fallout: Dolphins Drift Further as Underdogs

The betting market response was immediate. Miami, now 0-3, opened as roughly a touchdown-and-a-half underdog on the road against the undefeated Minnesota Vikings in Week 4, and that number has continued to move in Minnesota’s direction since Achane’s injury became official — from an opening line near Vikings -7.5 up to -10 at several books, with Miami’s moneyline pushing out toward +450 to +455. The total for that game has also come down, from an opening number in the low-40s to 39.5 or lower, reflecting oddsmakers’ expectations that Miami’s offense will have an even harder time scoring without its top playmaker touching the ball.

The injury also effectively closes the book on every preseason prop and futures market built around Achane. His rushing touchdown over/under, his Offensive Player of the Year longshot price, and any player-specific season-long wagers tied to him are now moot the moment he landed on injured reserve. That leaves the market’s attention on team-level numbers instead. Miami entered the season with a win total in the 3.5-to-4.5 range and was already trading toward the Under before Sunday; losing the offense’s best explosive threat while sitting at 0-3 only reinforces that lean heading into a difficult stretch of the schedule. The Dolphins’ odds to miss the playoffs, already among the shortest in the league at several sportsbooks, aren’t likely to lengthen anytime soon given this news, and the futures board for Miami’s backfield — from touchdown props to any remaining skill-position markets — will need to be rebuilt around Gordon and Wright rather than the player who was supposed to carry the offense into the second half of the season.
