Miner was operating the bolt machine and picked up a bundle of plates to step onto the man-up. He nearly missed the step but caught himself to regain balance. He hyper-extended his wrist. Later in the day he went to the ER, x-ray was negative. He continued to have soreness and was referred to an orthopedic on 1/6/15 where an x-ray revealed a fracture. He was placed on light duty.
