Her promoter Eddie Hearn says Taylor's homecoming is likely to happen at Dublin's 3 Arena instead of Croke Park.
Hearn claims the cost of staging a card at GAA H-Q is three times more expensive than Wembley Stadium.

Croke Park Stadium Director Peter McKenna says security costs got in the way of staging a Katie Taylor fight there in May.

McKenna says their fee is in line with that of Wembley, but there were mitigating factors.
