SANTA CLARA, Calif. (AP) — San Francisco 49ers running back Raheem Mostert and cornerback Emmanuel Moseley will both need season-ending surgery after getting injured against the Oakland Raiders.

Coach Kyle Shanahan said Friday that Mostert broke his arm and Moseley dislocated his shoulder in the 34-3 victory Thursday night. Both players have been placed on injured reserve and will miss the rest of the season.

Mostert had 41 carries for 297 yards this season as a backup to Matt Breida, including a 52-yard touchdown against Oakland.

Moseley played his first game of the season Thursday.

Shanahan also said he has not decided on who will play quarterback next game after Nick Mullens threw for 262 yards and three TDs in his debut. Mullens started ahead of C.J. Beathard, who was nursing a wrist injury. Shanahan said he will have a decision early next week when the players return from their long weekend.

The 49ers also re-signed backup quarterback Tom Savage a day after he was released.
