San Francisco 49ers running back Christian McCaffrey suffered a thigh injury during a matchup against the Atlanta Falcons and is now questionable to return. The four-time Pro Bowler exited to the locker room shortly after the incident but managed to jog under his own power for further evaluation. The severity of the injury remains unknown.

Before his exit, McCaffrey had recorded:

• 4 carries for 29 yards and 1 touchdown
• 3 receptions for 45 yards

This season, he has accumulated 77 carries for 350 yards and 7 touchdowns on the ground, along with 28 receptions for 190 yards over six games. As a dual-threat running back in Brock Purdy's offense, McCaffrey is a vital asset, especially given the 49ers' already weakened receiving corps, which is missing Mike Evans, Deebo Samuel, Demarcus Robinson, De'Zhaun Stribling, and Ricky Pearsall due to injuries.

The 49ers' running back room will lean heavily on rookie Kaelon Black and second-year RB Jordan James. Black, who currently leads the team with 11 carries for 60 rushing yards against Atlanta, is expected to take on a larger role with McCaffrey sidelined.

Historically, McCaffrey has led the team in rushing yards, except for 2024 when he was limited to just four games due to injuries. In his impressive 10-year career, he has amassed 1,735 rushes for 7,939 yards and 69 rushing touchdowns. McCaffrey was drafted by the Carolina Panthers in the first round of the 2017 NFL Draft and joined the 49ers in 2022.

As the game unfolds, the 49ers currently lead 14-12 against the Falcons, aiming to maintain their undefeated streak. CBS Sports will provide updates as more information becomes available.
