## Narrative

EE missed a step and felt a pop and twist in his knee when he landed. EE refused to seek medical treatment at the time. I received documentation of EE's treatment and restrictions on 12/1, which, at that time, made it reportable. Upon further investigation, I will determine if EE's absence during this time is a result of his injury.
