Chris Buescher's week just went from bad to worse.

The RFK Racing driver had a dramatic barrel-roll crash at the Coca-Cola 600 on Sunday, where he was caught up in a multi-car accident in the closing stages of the race.

Despite his car ending up on its roof, Buescher was uninjured in the incident, but on Thursday his team announced that he has tested positive for the COVID-19 virus and will have to miss the inaugural Cup Series race at World Wide Technology Raceway near St. Louis on June 5.

NASCAR Truck Series' Zane Smith will drive for Buescher in the No. 17 Ford Mustang in what will be his Cup Series debut. Smith races for Front Row Motorsports in a Ford F-150.
