## Narrative

During the bolting cycle a rock contacted the miner in the left knee causing ruptured ligaments.  The miner was seen at the site medic and referred to an orthopedic provider.  Due to the swelling the MRI was not completed and read until 3/15/23.  On that date the diagnosis of the ruptured ligaments was determined, and surgery scheduled.
