## Narrative

An employee was exiting a dozer at the B4 stacker area. As EE was getting off of the track EE's left foot landed on a rock that rolled, causing EE's right leg to twist. EE heard a pop. The pain began to increase later that day. The next day EE went directly to the clinic and was evaluated. EE was released with restrictions.
