This year's GAA Championship action gets underway today with last year's finalists Donegal taking on Tyrone in the first match of the Ulster Senior Football Championship live from Ballybofey, in Donegal. It will be interesting to see how Donegal perform without the legendary Jim McGuinness at the helm, particularly since they are going against the men that are led by the mighty oak that is Tyrone manager Mickey Harte, who you may have seen last Monday chatting to Pat Kenny on his new UTV Ireland show. Michael Lyster will of course be on presenting duties and is joined by Colm O'Rourke, Joe Brolly and Pat Spillane. (Throw-in 4.00pm)
