## Narrative

One of the Quality Control personnel while walking back into the Quality Control office tripped and fell on his right knee.  I took him to the doctor and he was x-rayed. He was told to follow up with another doctor so we set up an appointment with concentra and we are waiting for his cat scan results to come back in. He is off work per the doctor.
