Raiders lose starting running back in unofficial swap

Just hours after the Raiders signed Raheem Mostert on Thursday, the Dolphins have officially agreed to terms with Alexander Mattison, according to Fox Sports’ Jordan Schultz.

Mattison brings starting experience to South Beach, but his lone season with the Raiders was anything but memorable.
