Thursday at 8:45 a.m., jockey Abel Cedillo was at home near Del Mar, a place he did not expect to be on a weekday morning early in the summer race meeting.
Instead of working horses at the track, Cedillo was in the early days of a quarantine period, having tested positive for coronavirus on Tuesday. Cedillo was one of 15 Del Mar-based riders to test positive, the track announced on Wednesday. San Diego County health officials said in a statement released by the track that the affected riders, who were not all named, will be in quarantine for 10 days.
