The welterweight clash between Conor Benn and Adrian Granados has been postponed as Benn tested positive for COVID-19, DAZN announced on Thursday.
Benn (18-0-0) and Granados (21-8-3) were originally scheduled to meet on Saturday to headline the first main event of Fight Camp 2, a series of three consecutive weekend events to be held at Matchroom Boxing's Essex headquarters.
DAZN said a new date for the bout will be announced soon.
"Conor Benn has failed a COVID test this morning ahead of his fight against Adrian Granados," Eddie Hearn said in a video statement. "We will be conducting further PCR tests, but he will be off the card on Saturday."
The world title fight between Xu Can and Leigh Wood is set to headline the event alongside Tommy McCarthy's bout against Chris Billam-Smith.
Avni Yildirim's bout against Jack Cullen will be moved to the main broadcast.
James Dickens vs. Kid Galahad is scheduled to headline the second Fight Camp 2 event on Aug. 7, with Joshua Buatsi vs. Ricards Bolotniks lined up as the final fight of the series on Aug. 14.
