The GAA has confirmed the dates and throw-in times for round one of the new Tailteann Cup.
The 'northern section' games have been fixed for Saturday, May 28th - with the 'southern section' games scheduled for Sunday the 29th.
Leitrim's home against Antrim will throw-in at 2pm on Saturday week in Carrick-on-Shannon.
The game has also been selected as the livestream game on the GAAGO service.
Sligo's match with London will be played later that evening at Markievicz Park with a 6pm throw-in.
