It's level again in this tight Ulster derby as Rian O'Neill equalises for Armagh.

Very little between the sides so far.

Monaghan take the lead again.

Jack McCarron hits the post with a great strike from distance but Gary Mohan is on hand to fist over a point from the rebound.

Armagh's Rian O'Neill hits the post from a free.

It was from a tight enough angle but you'd probably expect O'Neill to score from there.

He gets another chance with a closer free a minute later and makes no mistake.

All square.

That was a left-foot strike of real quality from Jack McCarron as he edges Monaghan ahead for the first time in this match.

Monaghan have been playing three weeks on the bounce now, it will be interesting to see how that affects them the longer this game goes on.

Conor McCarthy runs from deep and places a measured shot between the posts with his left foot to get Monaghan's first point of the game and draw them level.

That's a decent chance for Armagh's Stefan Campbell but he is not able to get enough turn on the ball and his attempt drifts wide.

Patience is the name of the game for Monaghan in the early stages, with Armagh seemingly content to sit deep and look to hit them on the break.

Michael Bannigan looks to respond immediately for Monaghan but his strike from distance goes just wide.

That's what you call a nerve settler.

Aidan Forker strokes over a point for Armagh in the opening minute.

Right. Here we go.

The second of our quarter-final double-header is underway.

Aaron Kernan on GAAGO:

Armagh haven't made it to a semi-final in 18 years. It's unbelievable to think. They have their opportunity now, they need to go and win the game.

Armagh held off a spirited Monaghan fightback to come out on top by 1-14 to 1-12 in a tight opening-day National Football League Division One battle in Castleblayney back in January.

The big news for Armagh is that Rian O'Neill returns from suspension to take his place in the full-forward line.

Ciaran Higgins drops out of the panel, which is otherwise unchanged from the round-robin win over Galway in Carrick-on-Shannon a fortnight ago.

Monaghan make just one change from last week's preliminary quarter-final win over Kildare, with Ryan Wylie recalled and Darren Hughes dropping to the bench.

While Armagh enjoyed a rest last weekend, Monaghan were pushed all the way by Kildare, needing a last-gasp Conor McCarthy score to get over the line in Tullamore.

But there is rarely much between these sides. Armagh won this year's Division One encounter by two points while last year's National League meeting ended in a draw.

One down, three to go.

With holders Kerry being the first team to book their place in the semi-finals with that easy win over Tyrone, attention now turns to the Ulster derby between Armagh and Monaghan.

While Monaghan were last in the All-Ireland semi-finals in 2018, 2005 was the last time the Orchard men reached that stage.

Once again, we are at the ready to bring you live text commentary of the last-eight encounter, with a match report, reaction and highlights to follow.

Throw-in is 15 minutes away.

David Clifford on GAAGO:

The key thing today was to limit the turnovers. We played Tyrone here a few years ago with something like 33 turnovers, that was never going to win a game at this level. That was a big factor in how we won the game today.

We have scoring forwards, that's something we've put emphasis on, getting scores from elsewhere on the field because it becomes hard for defences to load up on the attackers.

Aaron Kernan on GAAGO:

Kerry have been on it today. They have without doubt showcased themselves as the front runners for the All-Ireland. It's been an excellent performance.

The full-time whistle goes and Kerry have cruised into the All-Ireland semi-finals with a convincing 12-point victory over Tyrone at Croke Park.

There was only three points between the sides at the break, but a strong start to the second half by the holders took the game away from the Red Hands and they strolled it in the end, with man-of-the-match Diarmuid O'Connor and Sean O'Shea getting their goals.

Kerry's Paudie Clifford and Conor Meyler of Tyrone are both sent off after being shown a second yellow card for a clash.

It's a goal and five points now for Sean O'Shea as he adds to Kerry's tally once more.
