The San Francisco 49ers formally placed Raheem Mostert on injured reserve, and they made a couple other moves. The team placed cornerback Emmanuel Moseley on injured reserve a day after promoting him from the practice squad. They also signed quarterback Tom Savage a day after releasing him.
Mostert broke his arm on a rushing attempt, while Moseley suffered a dislocated shoulder on a special teams play. Head coach Kyle Shanahan announced that Mostert had surgery on Friday, and Moseley will have surgery on Tuesday.
