San Francisco 49ers rookie defensive lineman Gracen Halton will miss the rest of the season after breaking his ankle against the Las Vegas Raiders, head coach Kyle Shanahan announced.

Halton was carted off on a stretcher with an air cast on his lower left leg after suffering the injury.

A fourth-round pick in the 2026 NFL Draft out of Oklahoma, Halton started six of his eight games. He recorded 15 tackles, including nine solo tackles and five tackles for loss, along with two sacks, one forced fumble and a fumble recovery returned for a touchdown.

After the game, 49ers linebacker Fred Warner spoke about Halton’s injury: “I’m sick for him. I know he was emotional getting on that cart, but I let him know, God, He does everything for a reason. So just keep his head up, and he’ll be all right.”
