49ers C Daniel Kilgore suffers injury Sunday, will not return

49ers center Daniel Kilgore suffered a leg/ankle injury in Sunday's game against the Broncos and will not return, the team announced.

Kilgore had his leg rolled on from behind during a play and was fitted with an aircast before being carted off the field. He was replaced by rookie Dillon Farrell. If the injury is serious, third-round pick Marcus Martin could eventually take over at center long-term.
