Mayo manager James Horan has fresh injury concerns ahead of Saturday's All-Ireland semi-final clash with Dublin.
Midwest Sport understands that Oisin Mullin picked up a knock at training this week which jeopardises his starting place for the crucial encounter.
The 2020 Young Footballer of the Year sustained a quad injury and now faces a race against time to be fit for Saturday.
Elsewhere, Padraig O'Hora - who came off injured in the Connacht Final win - is expected to be available for selection for the last four meeting.
The game will be live at 6pm on Saturday evening on Midwest Radio Sport, with thanks to Connolly's Irish Pub New York.
We'll also have live coverage of the ladies semi-final between Mayo and Dublin at 3.45.
Ahead of Saturday's double header, Midwest Radio's Michael D McAndrew will present a Sports Talkshop programme tonight between 10 & 11 where special guests include Keith Higgins and Ciaran Whelan.
