McCaffrey was a late scratch in last Monday's season opener, with the 49ers announcing that he would be inactive just a few hours before kickoff. The 49ers went on to handily beat the New York Jets despite missing the three-time Pro Bowl running back.
On Friday, McCaffrey was ruled out of San Francisco's Week 2 matchup against the Minnesota Vikings with the injuries. In a press conference the same day, 49ers head coach Kyle Shanahan told reporters that they were considering placing him on injured reserve, adding that McCaffrey had been in a lot of pain during practice on Thursday.
"It's on and off, but with yesterday having the most pain, something we're going to be discussing the next 24 hours," Shanahan said.
By being placed on IR, the earliest that McCaffrey could return would be Week 6. The 49ers will allow him time to recover before reassessing him in mid-October.
The loss of McCaffrey, the reigning NL Offensive Player of the Year, will be a tough blow for the 49ers. McCaffrey has been a crucial piece of the San Francisco offense since joining the team in 2022.
Jordan Mason will be San Francisco's starting running back going forward.
