Who Should I Start? Alexander Mattison or Dameon Pierce

Thursday, March 13, 9:35 PM

Former Las Vegas Raiders running back Alexander Mattison is signing an undisclosed deal on Thursday with the Miami Dolphins, sources told FOX Sports' Jordan Schultz. Earlier in the day, former Dolphins RB Raheem Mostert signed with the Raiders in free agency. The 26-year-old Mattison joined the Raiders in 2024 after spending his first five years in the NFL with the Minnesota Vikings. He eventually took over the lead-back role from a disappointing Zamir White and carried the ball 132 times for 420 yards and four touchdowns (a career-low 3.2 yards per tote) in 14 games (seven starts), adding a career-high 36 catches for 294 yards and another score. Mattison's move to Miami is a big downgrade, as he'll merely be competing for a change-of-pace role with Jaylen Wright behind unquestioned starter De'Von Achane. He'll be avoidable in most fantasy drafts this fall.

The Houston Texans placed both wide receiver Tank Dell (knee) and running back Dameon Pierce (undisclosed) on the Physically Unable to Perform list on Wednesday, according to NFL Network's Tom Pelissero. Dell suffered a dislocated knee and tore his ACL, MCL and LCL last year in Week 16, so he's not expected to practice at all in training camp or play at all in 2025. The 25-year-old has already had multiple surgeries on his knee in the offseason and may never be the same player if he's able to return in 2026. It's part of the reason why Houston drafted rookie pass-catchers Jayden Higgins and Jaylin Noel. Pierce, meanwhile, will be sidelined to begin training camp this summer with an undisclosed ailment, but he can be activated at any time. When healthy, he'll primarily be battling former Brown Nick Chubb for backup duties to Joe Mixon (ankle).
