Alexander Mattison Injury: How Does This Impact Dolphins’ Run Game?

The Miami Dolphins received tough news ahead of the 2025 NFL season as running back Alexander Mattison underwent season-ending neck surgery. The injury, sustained during a preseason game against the Chicago Bears, not only sidelines Mattison for the entire year but also shakes the foundations of Miami’s rushing attack as they look to stay competitive in a tough AFC.

Mattison, who joined the Dolphins in 2025, was expected to play a considerable role in Miami’s run game, bringing a combination of tough inside running and reliable pass-catching skills out of the backfield. The 27-year-old had garnered respect for his versatility and consistency, with the ability to handle a heavy workload and provide balance behind a strong offensive line. His absence creates an immediate void that the Dolphins must address quickly to maintain an effective rushing attack.

Head coach Mike McDaniel confirmed the severity of the injury, noting Mattison's surgery outcome and emphasizing that while the injury is serious, the team is hopeful for a full recovery. “Alexander is in good spirits and is focusing on his rehab, but we have to pivot and fill the gap he leaves on this roster,” McDaniel stated post-injury. With Mattison placed on season-ending injured reserve, Miami has already taken steps to reinforce their depth, signing veteran running backs such as Aaron Shampklin, who has experience albeit limited NFL action, and bringing in other candidates to bolster the backfield.

The impact on the Dolphins’ run game is multi-faceted. Mattison was expected to provide a substantial share of carries, complementing starter Raheem Mostert, who has been the primary workhorse. While Mostert is capable, the loss of Mattison means fewer options in sub-packages and a lack of a reliable change-of-pace back. Miami’s offense, known for its creative play-calling, relied on Mattison’s ability to handle diverse assignments ranging from power runs to check-down receptions. Without him, opponents can focus more on shutting down the lead back, making it imperative for Miami to find someone who can step up immediately.

Statistically, Mattison’s contributions go beyond raw rushing yardage. His ability to catch passes out of the backfield and pick up crucial yards after contact added a layer of complexity to Miami’s offense. The Dolphins averaged 4.3 yards per carry with Mattison active last season on limited touches, indicating efficient production. Losing that efficiency and the dynamic aspect he brought can alter scoring opportunities and time-of-possession advantages.

The Dolphins’ front office recognized the urgency of the situation. Reports indicate the team is not only relying on internal options like backups and undrafted rookies but also actively exploring free agent signings and potential trades. The addition of Shampklin, a journeyman back with brief NFL appearances, speaks to their current stop-gap strategy, but long-term stability remains a concern. McDaniel emphasized the importance of next-man-up mentality. “We trust our guys in the room and we’ll do whatever it takes to keep our run game strong,” he said.

Looking ahead, the challenge for Miami will be maintaining a balanced offensive attack that can alleviate pressure off quarterback Tua Tagovailoa. The run game’s effectiveness often dictates the success of Miami’s passing schemes. The loss of Mattison means the Dolphins’ offensive line might face more predictable defensive fronts if the run threat diminishes, which could impact overall offensive efficiency.

Alexander Mattison’s injury is a significant setback for the Miami Dolphins. His absence leaves a gap in the backfield that will require strategic roster moves and tactical adjustments. While the team is optimistic about Mattison’s recovery, the immediate focus is on recalibrating the run game to continue pressuring defenses and keeping Miami in the playoff hunt. How well the Dolphins adapt in the coming weeks could define their success in the 2025 season.
