The semi finals of the Eirgrid under-21 Ulster Football Championship take place tonight.
Armagh play Monaghan in Newry
And the holders Tyrone are up against Donegal at Celtic Park.
This game is a repeat of last year's final - Donegal reaching the semi final after edging out Derry in a closely contested quarter final in Ballybofey when Stephen McBrearty kicked the crucial free in injury time to secure a one-point victory.
Both games throw in at 8 o'clock - and we'll have full commentary of the Donegal/Tyrone semi final with Oisin Kelly and Martin McHugh
