Donegal lead Tyrone by two points at half time in their Ulster SFC quarter final in Ballybofey. 
In a tense and tight encounter a goal from Colm McFadden has been the difference between the sides.
A long ball inside from Michael Murphy was flicked on by Patrick McBrearty and McFadden was on hand to dispatch the ball into the back of the net.
Conditions have been difficult following heavy rain throughout the first half and as a result players on both sides have made numerous handling errors. 
Mark McHugh who wasn’t named in the starting 15 due to injury has come on in the place of Frank McGlynn who was withdrawn after suffering a recurrence of a hamstring strain.
