## Narrative

Drill helper was helping to remove a sub adapter from the roughneck by holding the elevated sub adapter prior to release. Once it was released, the weight of the adapter caused the sub to drop slightly causing the drill helper to pinch their middle finger between the threads of the sub adapter and drill rod; causing a laceration and fracture of the finger tip.
