Dolphins Sign Mattison in Swap with Raiders

The Miami Dolphins have signed veteran running back Alexander Mattison to a one-year contract, as first reported by Fox Sports. Mattison, who previously played for the Las Vegas Raiders, will join a backfield led by De'Von Achane and Jaylen Wright. The move comes as part of a swap with the Raiders, who signed former Dolphins running back Raheem Mostert. Last season, Mattison recorded 420 rushing yards and four touchdowns on 132 carries with the Raiders, and throughout his career, he has accumulated 2,790 rushing yards, 15 rushing touchdowns, and 1,012 receiving yards. While he is expected to serve as a backup in Miami, the Dolphins may still add more depth to their running game during the draft process.
