Katie Taylor and Amanda Serrano will finally square off this year in what's being billed as the "biggest fight in women's boxing".
The pair have been rivals for years, and almost got a fight made in 2020, but have now signed to main event at Madison Square Garden on April 30.
Taylor is the undisputed lightweight champion and one of the most famous sportspeople to ever come out of Ireland, while hometown fighter Serrano is a seven-weight world champion.
