49ers running back LaMichael James was carted off the field with an apparent left-arm injury early in Sunday's practice.
It's believed James got hurt in a pass-blocking drill. Coach Jim Harbaugh hovered over James on the ground before a trainer whisked him off to the locker room. James appeared to be supporting his left wrist with his right hand.
James had just become a top contender for the No. 2 running back role behind Frank Gore Friday, once Kendall Hunter sustained a torn anterior cruciate ligament and was lost for the season. Next up on the depth chart are Carlos Hyde and Marcus Lattimore. With Gore getting up in age, the 9ers RB2 can be fantasy worthy.
