Katie Taylor's fight with Amanda Serrano has been officially cancelled today due to the coronavirus pandemic.
Promoter Eddie Hearn confirmed the bout, which was due to be on the undercard of Dillian Whyte's heavyweight clash with Alexander Povetkin, is off.
The event was scheduled to take place in Manchester on May 2 and a new date is set to be announced in due course.
"In line with the BBBofC and Government guidelines relating to COVID-19, Matchroom Boxing have postponed all events scheduled to be taking place in May, including Dillian Whyte vs. Alexander Povetkin at Manchester Arena on 2 May," read the Matchroom Boxing statement.
"Subject to the developing situation, Whyte's Interim WBC Heavyweight World Title clash with Povetkin has been rescheduled to Saturday 4 July.
"The health and safety of the boxers, staff, event contractors and fans involved with our events remains the top priority for Matchroom Boxing and we thank everyone for their understanding.
"We look forward to bringing world-class boxing events back to these shores as soon as it is safe to do so. Our thoughts are with everybody affected by the COVID-19 outbreak at this difficult time."
Hearn said: "The problem is nobody knows, but we all hope we can return to some kind of boxing in June.
"Whether that's behind closed doors at first, or whether that's back with small-hall shows then we hope we can get to the bigger shows before the end of June."
