Level once more. Cool as you like from Armagh substitute Aidan Nugent as he delicately curls the ball from the right-hand side and over the bar. Tension is palpable as we approach the end of regular time.

Former Donegal captain and All-Ireland winner on GAAGoThis is a huge final ten minutes for Down. Not just to get into an Ulster Final but into the All-Ireland series, it's absolutely massive.

Pat Havern taps over a free for Down after Jason Duffy appeared to be harshly penalised for touching the ball on the ground. This wasn't in the script. Down lead by two with just over ten minutes of normal time remaining.

BBC Sport NI at ClonesEverything looked set fair for Armagh to reach this Ulster Final with the way the draw fell but they are looking decidedly nervy out there at the moment after that second Down goal.
The Mournemen are running directly at the Armagh defence when they have the ball and Kieran McGeeney's side are looking somewhat directionless at the moment. Still time for them to change matters obviously.

Down find the net again. The ball comes out to Ryan Magill, he stabs it goalwards and it deflects over the line. Scrappy? Yes, but Down won't care.

Last season's Ulster finalists have come flying out of the traps at the start of this second half. There has been a fire lit under Rian O'Neill at half-time it seems as he doubles Armagh's lead.

BBC Sport NI at ClonesI begged for a game to break out after 25 minutes and it has following Ceilum Doherty's goal.
Liam Devenney's refereeing is raising a few hackles among both sets of supporters it must be said.
Down great Sean O'Neill just walked by the press box a second ago letting us know his thoughts.
Immediately after the half-time whistle, Kieran McGeeney strode in Devenney's direction and that led his opposite number Conor Laverty to also get involved in the verbal exchanges.
In addition, Armagh selector Kieran Donaghy registered a protest with one of the linesmen but thankfully the players made their way to the dressing-rooms without any disturbances which isn't always the case these days.
