San Francisco 49ers rookie defensive tackle Gracen Halton was carted off late in the fourth quarter vs. the Las Vegas Raiders.

On third-and-10 with just over four minutes left in the game, Raiders quarterback Kirk Cousins hit Ashton Jeanty for a loss of 1 yard, as 49ers linebacker Dre Greenlaw wrapped him up. During that play, Halton had his leg hit by teammate Keion White, and the rookie remained down on the ground.

Eventually, the trainers got an air cast on his leg and carted him off the field.

Halton has had an impressive start to his NFL career, recording 15 tackles, two sacks, one pass defensed, one forced fumble and one fumble recovery in the first eight games of his rookie season, while playing nearly half of the team's defensive snaps.

The 49ers already swung a trade for a defensive lineman (DeForest Buckner), but if Halton is going to miss significant time, San Francisco may need to add another veteran to the room.
