Reigning Ulster football champions Cavan will begin their defence of the Anglo-Celt cup with a quarter-final against Tyrone.
The game will be the first taste of Championship action for the new Tyrone management team of Brian Dooher and Feargal Logan.
This year's Ulster Football Championship will begin with a preliminary round meeting of Down and Donegal. The winners of that tie will play Derry in the quarter-finals.
Fermanagh have been drawn to face Monaghan in those quarter-finals, while Armagh will take on Antrim.
There's potential for a repeat of last year's historic Ulster final in this year's semi-finals, with Cavan and Donegal on the same side of the draw.
