Who Should I Start? Alexander Mattison or Kenneth Walker III

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.

According to Adam Schefter of ESPN, Seattle Seahawks running back Kenneth Walker III (ankle) was placed on the injured reserve. As a result, Walker will miss at least the next four contests, which will keep him out for the remainder of the regular season. In addition, the Seahawks would have to advance to at least the NFC Championship to give Walker an opportunity to return to action. The Michigan State product sustained this injury during last weekend's loss to the Minnesota Vikings. As a result, fantasy managers should expect Zach Charbonnet to lead the backfield for the foreseeable future. When put in the starting role, Charbonnet has performed very well. During Weeks 14 and 15, Charbonnet averaged a stellar 25.9 PPR points per game. He should be viewed as a top-12 option on Thursday evening when he faces the Chicago Bears. Kenny McIntosh will move up to the No.2 spot and could see a slight increase in opportunities.
