Tyrone manager Mickey Harte wary of 'formidable' Donegal

Tyrone manager Mickey Harte says his side face a 'formidable' challenge against All-Ireland champions Donegal in their Ulster SFC first round tie on 26 May.

"We are conscious that everything steps up a gear when the Championship rolls round again and our first match is the most difficult you could face," said Harte at the launch of the Ulster Championship in Belfast.

"One game could turn our season on its head and land us in the qualifiers," added the Red Hands boss.

Harte is confident that Stephen O'Neill and Peter Harte will both be fit for the game with Donegal.
