Despite receiving the second-round RFA tender from the 49ers this week, Jordan Mason will not play in San Francisco next year. The fourth-year running back has been traded to the Vikings, per his agency (via Ian Rapoport of NFL Network).

As part of the deal, Mason has agreed to a two-year Vikings contract, Rapoport notes. The pact has a maximum value of $12MM and includes $7MM guaranteed at signing. Per Rapoport and colleague Tom Pelissero, the trade consists of a 2026 sixth-round pick being sent from Minnesota to San Francisco. The teams will also swap picks No. 160 and 187 in this year’s draft.

Mason totaled only 83 carries during his first two seasons, but in 2024 he was a key member of the 49ers’ ground game. Christian McCaffrey‘s Achilles issues opened the door for the former UDFA to see notable usage, and he received 153 carries on the year. Mason’s success (880 scrimmage yards, three touchdowns, 5.2 yards per attempt average) made it clear San Francisco would look to keep him in the fold moving forward. The decision to apply the second-round tender appeared to lock him into a $5.3MM salary for 2025.

As a result, the 49ers would have been in line for a second-round pick as compensation in the event Mason signed an offer sheet with an outside team which they declined to match. Now, he will be on the move by means of a swap. San Francisco still has McCaffrey on the books, along with Isaac Guerendo and Patrick Taylor. An addition in the 2025 draft – which features several highly-regarded RB prospects – would come as no surprise given this deal.

For the Vikings, meanwhile, Mason will allow for more of a tandem in the backfield moving forward. Aaron Jones impressed while playing on a one-year pact in 2024, setting a new career high in rushing yards. That yielded a new agreement just before the negotiating period opened, and Jones is now attached to a two-year, $20MM pact. While the Vikings expressed a desire to keep the former Pro Bowler in the fold, they also made it clear they intended to reduce his workload after Jones handled 306 touches (the most of his career) in 2024. Mason will help achieve that goal.

The latter recorded double-digit carries seven times in his 12 appearances last year. Mason suffered an ankle sprain in Week 13, however, and the injury ended his campaign. His absence will be felt on a 49ers team which lost Elijah Mitchell to the Chiefs in free agency. Even if Guerendo takes on a larger role next season (after logging 84 carries as a rookie), at least one addition in the backfield can be expected.

More to come…
