Just after hearing that his Kentucky Derby mount, Art Collector, wouldn’t be entered in the race due to a minor foot injury, jockey Brian Hernandez, Jr. found out that he had tested positive for COVID-19 on Monday. He was subsequently taken off all mounts at Churchill on Tuesday and Wednesday.

The 34-year-old rider then took an antibody test on Tuesday, which was also positive.

According to the Daily Racing Form, Hernandez consulted with both local health officials and Churchill representatives, and eventually it was decided to allow him to resume riding on Thursday, “on the basis that he is not an infectious danger to others.”
