All-Ireland champions Tipperary entertain Ulster champions Antrim in the first of the afternoon's two hurling quarter-finals at Croke Park.
Tipperary are strong favourites but the Antrim boss believes his team can create a shock.
The throw-in for Tipperary v Antrim is 2.15pm.
On the same bill Galway and Clare will face each other. The Tribesmen will start as narrow favourites today.
