The Ulster Championship, deemed the most competitive of the GAA provincial qualifiers, should live up to expectation as it delivers the clash of Donegal and Armagh in this quarter-final pairing. A feisty league meeting between these sides resulted in six players being issued with suspensions. This much-anticipated return fixture will be presented live and uninterrupted from MacCumhaill Park, Ballybofey by Mark Sidebottom in the company of Oisin McConville, Martin McHugh and Peter Canavan. Thomas Niblock and Martin Clarke provide the commentary.
