Katie Taylor’s rematch with Amanda Serrano is off after the Puerto Rican sustained an injury.
The pair were due to fight on 20 May in Dublin for the undisputed lightweight championship.
The rematch was agreed after their thrilling first fight at a sold out Madison Square Garden in New York last year, which saw the Irish woman prevail by split decision.
But Serrano, who defeated Erika Cruz on points earlier this month, is now unfit to fight in May, forcing a postponement.
A statement from Matchroom said: “Due to an injury sustained by Amanda Serrano, Matchroom Boxing and Most Valuable Promotions regret to announce that the Taylor-Serrano II bout on May 20 in Dublin will not go ahead as planned.
“The teams are in discussions about finding a revised date for the bout. Further details will follow in due course.”
Serran rebounded from her only professional defeat nicely, taking points victories over Sarah Mahfoud and Cruz.
While Taylor maintained her unbeaten professional record with a win over Karen Carbajal.
The pair may have met at Croke Park, with the 82,000-seater stadium in the running to host the rematch.
Eddie Hearn was poised to hold discussions with Conor McGregor to help facilitate the event, which many believe would have been the biggest women’s fight in boxing history.
Taylor is still the undisputed lightweight champion and, despite defeat, Serrano has remained unified featherweight champion.
