A frantic period as Andrew Murnin somehow gets his shot away despite being confronted by a sea of Donegal bodies, but it's blocked! Stefan Campbell picks up the pieces but fires wide.

Armagh defend heroically to thwart Jamie Brennan and Jason McGee.

Brennan is subsequently yellow carded for a high challenge as Armagh look to break out.

Donegal will try keep the ball as long as possible, they won't try to see the game out this early, but they will be patient and will try fatigue Armagh.

Not for the first time today, cap-wearing goalkeeper Ethan Rafferty rises above two Donegal players to secure a Shaun Patton kick-out.

He decides to take on a two-pointer to level the game but it sails wide. That would have been a superb piece of individual play from the Armagh keeper.

Lovely bit of inter-play between Darragh McMullen and Stefan Campbell, who knocks over his second point.

Campbell is fouled after taking the shot by Michael Langan, who is booked.

Two-point game.

Clever game management by Donegal as they patiently probe at the Armagh defence before Jamie Brennan pulls the trigger...it goes wide though!

At the other end, Stefan Campbell surges forward but doesn't execute his shot well this time.

There's still a goal in it.

Jason McGee calms the Donegal nerves a wee bit with a nicely taken score. Ethan Rafferty was stranded there, but thankfully for Armagh, there was no Donegal goal at the end of the move.

Donegal are penalised for not following the three-man rule. Oisin O'Neill takes the free out to two-point range...and scores!

Huge moment for Armagh. Just two in it and with 16 minutes still remaining.

Here is how Hugh McFadden swept home a goal for Donegal at Clones.

Donegal take the sting out of the game by keeping the ball, but Ryan McHugh's shot at the end of it all goes wide.

The only man that has stepped up for Armagh going forward has been Conaty. They need more and maybe Campbell will be that injection.

This is exactly what Armagh needed as Oisin O'Neill collects Conor Turbitt's pass and scores.

Three in a row for Armagh.

Right on cue!

Stefan Campbell knocks over his first score with his first involvement.

Armagh need the next score.

They get the next score and no surprise to see Oisin Conaty wheeling away after splitting the posts. His fifth of the day.

Stefan Campbell is also on the pitch, replacing Callum O'Neill. Campbell is a fantastic impact player and Armagh need to see that over the next 20 minutes.

This is quickly becoming alarming for Armagh as Ciaran Moore makes it 1-3 without reply for Donegal.

A seven-point lead.

Conor O'Donnell scores another Donegal point.

An absolutely crucial period of the game. A Donegal goal, two missed Armagh goal chances and another couple of Donegal scores.

The holders lead by six.

How has that not gone in?!

Ben Crealey's low shot takes a deflection, hits the post and trickles across the line before going wide. How have Armagh not scored at least one goal in the past two minutes?!

Michael Murphy fires over a fine point. Donegal lead by five with 25 minutes left.

Deary me!

Armagh look to immediately respond with a goal of their own but Darragh McMullen blasts wide after doing brilliantly to fashion half a yard of space.

Chaotic few minutes.
