The San Francisco 49ers placed star running back Christian McCaffrey on injured reserve Saturday, ensuring that he will miss at least the next four games with calf and Achilles injuries.
The move is a shocking departure from the optimism of less than two weeks ago, when McCaffrey was a last-minute scratch for the 49ers’ season-opening win over the New York Jets.
McCaffrey missed the entire pre-season with what was reported as calf soreness. In the regular season, teams are required to submit official injury reports, and McCaffrey’s designation included Achilles tendonitis.
Last year’s rushing champion will miss a minimum of four more games, with the earliest possible return date coming on Oct. 10.
The 49ers face the Minnesota Vikings, Los Angeles Rams, New England Patriots and Arizona Cardinals over their next four, but there is no guarantee that McCaffrey will return when first eligible.
San Francisco ruled McCaffrey out for Sunday’s game in Minnesota on Friday, with head coach Kyle Shanahan publicly acknowledging for the first time that the 2023 Offensive Player of the Year could end up on IR.
“Yesterday was his worst day,” Shanahan told reporters. “It's on and off, but with yesterday having the most pain. It's something we're going to be discussing together in the next 24 hours.”
The loss is a massive one for the reigning NFC champions, who went 12-5 in McCaffrey’s first full season with the team last year.
With Elijah Mitchell already placed on IR before the start of the season, the only trusted running back on San Francisco’s roster is Jordan Mason, who ran the ball 28 times for 147 yards and a touchdown.
McCaffrey’s extended absence could also result in Deebo Samuel getting more snaps at running back, a look that was more common before the 49ers traded for McCaffrey during the 2022 season.
This is McCaffrey’s first IR stint since joining the 49ers. The Stanford product played a combined 10 games in the 2020 and 2021 seasons due to ankle and hamstring injuries.
McCaffrey led the NFL with 2,023 yards from scrimmage last season and tied with Raheem Mostert for the league lead at 21 touchdowns.
