Oisin Gallen off for Donegal after two minutes of extra-time, how big could that be?

Who will be the hero?

Confirmed: 28,896 sell out in Clones today.

Are the Armagh fans going to see penalties, like they did 12 months ago?

There's a good chance of it.

Even with Tiernan Kelly's effort, it just felt like we were destined for extra-time there.

Jim McGuinness seemed to have an extremely angry reaction at the final whistle there - it may have been because the board indicating the three added minutes to be played only went up 30 seconds or so before the whistle?

Anyway, we've another 20 minutes of this.

There's nothing between the two teams.

If I'm honest I'm a wee bit disappointed when Armagh went four up that they didn't see it out.

Fair play to Donegal. They showed a lot of character and a lot of fight to get back into the game when it didn't look likely.

Extra-time again in the Ulster final!

Donegal did well to claw themselves back into that. Can they go on and win it now?

Tiernan Kelly calls for the mark and this time Armagh will go for the point.

WIDE!

Three minutes added on at Clones.

The tension is off the charts.

Donegal get the turnover. Will Armagh not rue taking on some of those opportunities?

Campbell calls for the mark but opts to knock the ball backwards rather than take the shot on.

Into the final minute...

Another Ulster final goes right down to the wire.

Two minutes for someone to be a hero and get their hands on the Anglo Celt.

Niall O’Donnell brimming with confidence after some of his scores today but that one is a bit too ambitious.

McGuinness looks none to happy about the decision making.

Aidan Nugent on for Armagh.

Oisin O'Neill on for Ben Crealey for the last five minutes.

Players are losing their footing all over the place here but not so Patrick McBrearty.

Donegal's captain. As cool as you like. Four in a row for Donegal. All square. Armagh haven't scored in 10 minutes.

The counter is on as Jason McGee sets Donegal moving forward but Armagh do well to get back.

Patrick McBrearty steps up...over the bar!

We're level at Clones.

Donegal trying to draw Armagh out of their shape but space is hard to come by.

They still search for the equalising point.

Eight minutes to go.

I've been impressed by Donegal so far in this championship. Two or three points down they still stick to their gameplan and keep the scoreboard ticking over.
