49ers rookie defensive tackle Gracen Halton was placed on injured reserve on Tuesday.
The team’s announcement of the move did not come as any surprise. Halton broke his ankle in last Sunday’s win over the Raiders and he will miss the rest of the season as a result.
Halton joined the 49ers as a fourth-round pick in April. He started six of the team’s first eight games and ends his rookie season with 15 tackles, five tackles for loss, two sacks, a forced fumble and a fumble recovery for a touchdown.
DeForest Buckner, Osa Odighizuwa, Sebastian Valdez, and James Thompson are the remaining defensive tackles on the 49ers’ roster.
