The 49ers lost rookie defensive tackle Gracen Halton to injury Sunday — and he will miss the rest of the season, according to head coach Kyle Shanahan.

Halton was carted off with during the final minutes of the matchup against the Raiders, but his impact was palpable as the entire team walked on the field to say goodbye before he exited. The rookie sustained an ankle injury, which appeared to be severe given the air cast was put on.

Halton’s infectious personality and laugh has become a locker room staple as evidenced by San Francisco’s bench clearing to form a huddle around the defensive tackle.

49ers star linebacker Fred Warner took off his helmet and hugged Halton before he made his departure. The rookie’s absence is another obstacle for the team to overcome, but the 49ers are no strangers to injuries.

The entire wide receiver room has been plagued injury woes throughout 2026 and the 49ers played without Mike Evans, Deebo Samuel and Christian Kirk Sunday.

San Francisco seemingly fortified its defensive line with the acquisition of DeForest Buckner, but Halton’s injury certainly becomes another challenge for the team as it looks to make a deep playoff run.

The 49ers defeated Las Vegas 38-17, but still took a huge loss with the injury to Halton.
