49ers running back Christian McCaffrey was listed as limited for San Francisco’s practice on Thursday after suffering a calf/Achilles injury that has sidelined him for training camp and the preseason.

Head coach Kyle Shanahan told reporters before practice that the Achilles injury is nothing new and is related to the calf strain he suffered in training camp in early August. He expressed no concerns about McCaffrey’s playing time for Monday’s season opener against the New York Jets.

McCaffrey and the 49ers downplayed the injury as minor throughout training camp. McCaffrey said on Aug. 9 that his absence from practice was a “warning” and that he would be ready to play if the 49ers had a game that day.

Shanahan has said throughout the preseason that he expects McCaffrey to be ready to play in Week 1. McCaffrey participated in practice for the first time on Tuesday and is on track to play Monday night.

McCaffrey, a three-time All-Pro, led the league in rushing (1,459 yards) and yards from scrimmage (2,023) in 2023 and was tied with Dolphins running back Raheem Mostert for the NFL’s all-time leading touchdown leader (21). He was named the NFL’s Offensive Player of the Year by the Associated Press.

McCaffrey’s dynamic playmaking skills as a runner and pass receiver are crucial to the success of San Francisco’s offense. The 49ers enter the season fresh off a Super Bowl appearance and are among the favorites to return to the Super Bowl from the NFC.
