The dislocated elbow 49ers running back LaMichael James sustained Sunday is the third of his career, reports ESPN.com. He suffered the same injury in 2011 and in high school.
James, who is out a month, got hurt on a blitz pickup drill when he was blown backward by inside linebacker Michael Wilhoite, according to the Sacramento Bee. James has gotten injured before the regular season in each of his three NFL seasons. He hurt his ankle in the 2012 preseason and sprained a knee ligament in last year's preseason.
