## Narrative

An offsider for the 3175 jumbo was gathering bolting supplies in the NRS. While lifting sections of wire to place blocks, the worker felt a pop and burning sensation in their right lower bicep. Thinking it was minor, they finished the task, but after reporting it to the jumbo operator, the shift supervisor was notified and the worker was brought to the surface.
