Eddie Hearn has casted doubt on Katie Taylor's rematch with Amanda Serrano taking place at Croke Park.
And the promoter has pointed the blame at 'operational costs' and said hosting the event at GAA HQ would cost twice the amount as if it took place at London's Wembley Stadium.
Serrano is in action this weekend with Mexico's Erika Cruz and a rematch against Taylor is likely if she gets past her opponent.
