Update on Mitchell's injury

Niners HC Kyle Shanahan said Wednesday that he hoped RB Elijah Mitchell's shoulder injury was merely a stinger but that it's actually a "little worse," according to Eric Branch of the San Francisco Chronicle. "He's got a chance" to play in Week 3, Shanahan added. We'll have to track Mitchell's progress through the week. The other injuries around the San Francisco backfield make it tough to know right now what the succession plan would be if Mitchell's out.
