Who Should I Start? Jordan Mason or Brian Robinson Jr.

Wednesday, December 24, 3:27 PM

Minnesota Vikings running back Jordan Mason (ankle) has been ruled out for the Christmas Day game on Thursday versus the division-rival Detroit Lions after missing practice from Monday through Wednesday, per the team. Mason was always viewed as a long shot to play on a short week after injuring his ankle in the Week 16 win over the New York Giants on Sunday. The Vikings have nothing left to play for in 2025, so they were not going to push Mason to play. With the 26-year-old on the sidelines on Thursday, Aaron Jones Sr. should be in line for more backfield touches against the Lions. However, his fantasy upside will be tempered with inexperienced backup quarterback Max Brosmer set to start in place of the injured J.J. McCarthy (hand). Jones should be considered more of a touchdown-dependent, high-end RB3/flex for the matchup against the Lions.

Across 14 games this season, San Francisco 49ers running back Brian Robinson Jr. has recorded 349 rushing yards and two touchdowns on 81 carries. The 26-year-old has spent the entirety of the 2025 season in a backup role behind star 49ers running back Christian McCaffrey. Robinson Jr. has yet to record double-digit carries in a game in 2025 and has just seven receptions on the season, so his standalone fantasy value is limited. However, if McCaffrey were to suffer an injury, Robinson Jr. would immediately become a viable starting fantasy running back. He's proven he can succeed in a lead-back role in the past, racking up 799 rushing yards and eight touchdowns on 187 carries across 14 games with the Washington Commanders in 2024. In fantasy leagues with 12 or more teams, Robinson Jr. is worth rostering just in case McCaffrey goes down.
