We're back in GAA HQ this weekend for the All-Ireland Senior Football Championship semi-final and it certainly looks set to be quite the clash as Mayo take on Tyrone from 3.30pm. The lads from the West put in some performance to send title holders Donegal out of the competition with the tail between the legs, but do they have what it takes to defeat the men from Ulster and make it all the way to the final? Michael Lyster is at the helm as always, with Colm O'Rourke, Joe Brolly and Pat Spillane on hand for some analysis.
