Ulster U21 football final places up for grabs
Places in the Ulster U21 final will be settled on Wednesday night when Tyrone, Armagh, Donegal and Monaghan do battle in their respective semi-finals.
Tyrone have not won the U21 title since 2006 but lost two finals to Cavan in 2011 and 2012, while their semi-final opponents Armagh last won in 2007.
The game has been moved to Breffni Park due to unplayable Brewster Park pitch.
In the other semi-final, last year's beaten finalists Donegal and Monaghan meet in Healy Park, Omagh.
Donegal lost back-to-back Ulster finals to Cavan but got revenge in this year's quarter-final with a late Ryan McHugh goal.
They last won a provincial title at this grade in 2010, before losing back-to-back deciders to the Breffni county in 2013 and 2014.
Their semi-final opponents, Monaghan, have not won an Ulster U21 title since 1999 but will be backboned by many of the players who won an Ulster minor title in 2013. They defeated Derry 0-15 to 1-8 in the quarter-final.
Many of the players who helped Tyrone win the Ulster minor title in 2012 and reach the All-Ireland minor final in 2013 will be in action in Enniskillen. Senior panellist Cathal McShane kicked three second-half points in their quarter-final win over Fermanagh.
Armagh defeated Antrim in a rearranged quarter-final, after the floodlights in the Athletic Grounds failed when they were first scheduled to meet two weeks ago.
The Ulster U21 final will take place on 8 April.
