Matchroom Boxing have confirmed that Katie Taylor will not fight Amanda Serrano in Dublin in May due to an injury suffered by the Puerto Rican.
Taylor defeated Serrano in an all-time classic at Madison Square Garden last April, with a rematch between the pair called for in the immediate aftermath of the New York bout.
An instant rematch fell through over the failure to secure Croke Park last September, with Taylor instead fighting Argentina's Karen Elizabeth Carabajal in London a month later, while Serrano opted to become the undisputed featherweight champion by defeating Sarah Mahfoud and Erika Cruz Hernandez.
