## Narrative

Miner was replacing cutting edges on a 980G loader and in the process EE was pulling the center plate from underneath the bucket so it can be picked up with a boom. As the miner released the cutting edge and stood up, EE felt a ""pop"" in the lower right side of the back. This resulted in a muscle strain in EE's lower back.
