It was reported on Monday that Mattison would be out for the season. Miami will likely look to add a running back.

Miami Dolphins running back Alexander Mattison underwent a season-ending surgery for the neck injury he suffered during the preseason opener.

Fantasy Impact

Mattison spent 2024 with the Las Vegas Raiders, rushing for 420 yards (second-fewest of his career) and 3.2 yards per carry (fewest in his career). Neck injuries are always scary, and this could have a direct impact on his future in the NFL. He will be out for the rest of the season, but his status for 2026 and beyond is very much in question.

Alexander Mattison “is experiencing neck and shoulder soreness” after leaving the Dolphins’ preseason Week 1 game early.

Fantasy Impact

Mattison has been drawing high praise out of Dolphins camp. There should be an update on his status this week.

The Dolphins have signed RB Alexander Mattison.

Mattison will likely enter training camp competing for a backup role behind De'Von Achane. Fantasy managers should expect the veteran to see limited touches to kickoff the season.

Alexander Mattison rushed for 20 yards on six carries in the Raiders 34-20 loss to the Chargers. He caught 4-of-5 targets for 11 yards.

Mattison split time with Chris Collier in the backfield for the Raiders final game of the season. He will finish the season with 420 rushing yards and four touchdowns on 132 rushing yards.
