Clifford tested positive for COVID-19 on April 22. He then returned two negative tests the next day before again testing positive on April 24. He has missed the Magic's past five games and will not be present for Monday night's game in Detroit because the team traveled Sunday.
Clifford has received both doses of the Moderna vaccine, getting the second one the same day he tested positive on April 22. He is not yet considered fully vaccinated by the Centers for Disease Control and Prevention protocols; two weeks have not passed since his final dose. He told ESPN's Adrian Wojnarowski last week that he had experienced no side effects from getting the vaccine and was asymptomatic.
Clifford has dealt with some health issues in the past. He missed 21 games because of problems caused by sleep deprivation during the 2017-18 season, when he coached in Charlotte. He also left Orlando's game vs. the Timberwolves in March 2020 after experiencing dizziness caused by dehydration.
Magic assistant Tyrone Corbin has filled in on the Orlando bench during Clifford's absence.
