## Narrative

While replacing a punch plate deck on the bull-screen, the Miner positioned self above the screen chute at the top of the rubber wear material.  As the Miner was maneuvering the screen, EE perceived from EE's view that EE was going to take a step up, but was actually stepping down.  The unexpected step down and resulting jolt caused the Miner's knee to twist.
