San Francisco 49ers head coach Kyle Shanahan said on Tuesday that tight end George Kittle has been placed on injured reserve due to a hamstring injury. Per ESPN’s Adam Schefter, early reports indicated that Kittle may be sidelined for multiple weeks. Kittle is in his ninth season, and has made the Pro Bowl in four straight seasons and six of the last seven. In addition to Kittle’s injury, QB Brock Purdy also sustained multiple injuries during Sunday’s game; Shanahan confirmed that he is now dealing with a toe injury and a shoulder injury. Specifics of both injuries are not yet known, but Shanahan said Purdy’s toe is worse than his shoulder.
