After Toye is booked for a clothes-line challenge on Justin McMahon, Sean Cavanagh points the free and McCurry then levels proceedings.

As the Ballybofey noise levels increase following a number of vigorous challenges, Christy Toye fists over a Donegal point when there is more than a sniff of a goal chance.

With all the possession Donegal had in the first 20 minutes they should be further ahead.

But Sean Cavanagh's free gets Tyrone scoring again as there is only a point between the teams.

There is a bit of a scoring lull as McCurry misses a 40-metre free and Donegal's McElhinney pulls a shot wide at the other end.

Tyrone seem to be in a hurry when on the attack and are taking the wrong options and rushing their shots.

However defender Justin McMahon's point means he has outscored his direct opponent Michael Murphy. How long will that last?

Murphy has not been an influence on the game yet but that's surely bound to change.

Peter Harte's forges a goal chance for himself only to see his shot superbly saved by Durcan but Justin McMahon clips the rebound over the bar.

Donegal regroup from the shock of McCurry's goal as Colm McFadden kicks a point with his weaker right foot and McElhinney then adds another.

The Donegal defence was asleep but what a lovely finish from Darren McCurry

Donegal look in total control after Martin McElhinney slots their fourth point but Tyrone hit back emphatically as a totally unmarked Darren McCurry fires to the net past Paul Durcan. Suddenly there's only a point between the teams.

Quite a contrasting start for the two number threes.

Neil McGee lets Tyrone's under-21 star Cathal McShane know that the step up to senior football is a big one by winning the first ball that came in to them, while at the other end, Paddy McBrearty skins Tyrone full-back Ronan McNamee for Donegal's second point.

Christy Toye slots a third Donegal point after only five minutes. Tyrone's defensive left flank looking rather shaky.

"Donegal well on top here - Tyrone need a score."
