We're only at the preliminary stage, and yet such drama. Who is going to book their place in the last eight?

Unbelievable character from the Tyrone lads.

They pushed right up. That bit of grit is what was needed, I thought Tyrone were too soft in the first half.

In an added incentive for Tyrone, Armagh will contest the extra period with a man less as Darragh McMullen was dismissed moments before Ben McDonell's equalising goal.

Going into extra time, boys will be tired but they are going to have to be brave and make good decisions.

I think Tyrone will be disappointed to be honest to not come away with the win here with some of the chances that they missed.

To give away the ball so easily at the end as well, but their tails will be up.

What a storming finish that was.

Just as it seemed some Oisin O'Neill magic had saved Armagh, Tyrone fashion that goal from Ben McDonnell.

Incredible drama but were we expecting anything else?

We've another 20 minutes of then and then, who knows...

It’s really sprung to life at the Athletic Grounds.

Armagh have lost their shooting touch after three wides in a row and they’ve been punished with Tyrone now hitting the front.

We’re set for a gripping final 15 minutes.
