Donegal's footballers will take part in a major fundraiser in memory of Michaela McAreavey next month.
Jim McGuinness's men go up against a selection of Ulster stars as the main attraction of the "Match for Michaela - A Festival with Football," details of which were announced by Ulster GAA yesterday.
The event, which will be compered by RTÉ DJ Hector Ó hEochagáin and feature music including X Factor finalist Janet Devlin, takes place in Belfast's Casement Park on Saturday 3 November.
The daughter of Tyrone football manager Mickey Harte and husband of Down inter-county player John McAreavey, Michaela's murder while on honeymoon in Mauritus in January 2011 left the GAA community in shock.
All funds raised will go to the Michaela Foundation, set up last summer to celebrate the 27-year-old's life and inspire her values in young people.
Michaela's father Mickey Harte, will help Armagh manager Joe Kernan take charge of Ulster for the challenge match.
