Donegal beat Derry 0-16 to 0-15 in their Ulster quarter-final on Sunday thanks to a superb late point from Paddy McBrearty.
The Donegal forward had been well shackled by Derry defender Chrissy McKaigue for most of the game.
In the minutes before McBrearty's score, he had put Donegal ahead for the first time - 0-15 to 0-14 - from a free. Shane McGuigan soon kicked an equaliser, also from a free.
With the 74 minutes on the clock, and four minutes of injury time down to be played, McBreaty kicked a sensational point from near the sideline just a few metres inside the 45m line.

The game was not over there though. Referee David Coldrick played another 75 seconds, but no one from Rory Gallagher's side took a shot at the equaliser as they continually recycled the ball on the Donegal 45m line.
The match began to turn with just over 20 minutes to play. Derry had been four points ahead, but the introduction of Michael Murphy and Odhrán McNiallais for Donegal turned the game in their favour.
Donegal will play Tyrone in the Ulster semi-finals next weekend.
