We are just moments away from throw-in as Amhrán na bhFiann echoes around Croke Park.

The atmosphere is building nicely at GAA headquarters, with Dublin supporters continuing to stream into the Davin Stand while Donegal's travelling support has also turned out in impressive numbers for this winner-takes-all encounter.

There is a palpable sense of anticipation around the stadium as two of Gaelic football's traditional heavyweights prepare to battle for a place in the All-Ireland quarter-finals.

Who will be back at Croke Park next weekend, and whose championship journey ends this afternoon?

Both managers have made late alterations to their starting line-ups ahead of this afternoon's knockout clash at Croke Park.

Donegal show two late changes from the side originally named, with Max Campbell replacing Ryan McHugh and Shea Malone coming in for Oisin Gallen.

The changes come after Jim McGuinness had already made one switch from the team that lost to Cork last weekend, with Gavin Mulreany replacing Shaun Patton in goal. Gallen's withdrawal is a notable one, with the forward having scored 14 points across the Ulster Championship and All-Ireland series this summer.

Dublin have also made three late changes. Colm Basquel comes into the attack in place of Seán Bugler, while Peadar Ó Cofaigh Byrne replaces Eoin Kennedy. There is also a change among the substitutes, with Cormac Gallagher drafted into the matchday squad in place of Caolan McColgan.

Basquel's inclusion adds further experience to a forward line that already contains Con O'Callaghan, Ciarán Kilkenny and Cormac Costello as Ger Brennan's side look to secure a place in the quarter-finals.

Donegal: Gavin Mulreany; Eoghan Ban Gallagher, Brendan McCole, Peadar Mogan; Max Campbell, Caolan McGonagle, Finnbar Roarty; Jason McGee, Hugh McFadden; Shane O'Donnell, Michael Langan, Ciaran Moore; Conor O'Donnell, Michael Murphy, Shea Malone.

Subs: Shaun Patton, Paul O'Hare, Jamie Brennan, Ryan McHugh, Daire O'Baoill, Sean Martin, Oisin Gallen, Cormac Gallagher, Ciaran Thompson, Turlough Carr, Kieran Gallagher.

Dublin: Evan Comerford; Lee Gannon, Nathan Doran, David Byrne; Sean MacMahon, Charlie McMorrow, Peadar Ó Cofaigh Byrne; Theo Clancy, Brian Howard; Colm Basquel, Con O'Callaghan, Niall Scully; Paddy Small, Ciarán Kilkenny, Cormac Costello.

Subs: Hugh O'Sullivan, Tom Lahiff, Liam Smith, Greg McEneaney, Cian Murphy, Sean Guiden, Josh Bannon, Ross McGarry, Eoin Kennedy, Seán Bugler, Tim Deering.

Clare marched into the semi-finals of the All-Ireland Senior Hurling Championship with a 0-29 to 0-16 win over Dublin on Saturday.

However, the game was marred by an incident late in the game which saw Clare's David Reidy stretchered off and taken to hospital Following a high hit by Brendan Kenny which saw the Dublin player sent off.

"It was scary enough," Clare forward Shane O'Donnell told RTE Sport.

"Fortunately, I think he will be OK. We’ll see in a few days, but he looked better than he did in the first 30 seconds of it."

It's since been confirmed Reidy has been discharged from hospital and is recovering.

Clare's semi-final opposition will be decided by the outcome of today's second quarter-final between Cork and Offaly in Thurles [15:30 BST].

Should Cork prevail, they will meet Galway in the last four with Clare taking on Limerick, but an Offaly win will send them into a meeting with the Munster champions with Clare then paired with the Tribesmen.

Holders Kerry produced a ruthless display to see off Armagh by 4-18 to 0-17 to reach the quarter-finals of the All-Ireland SFC at Fitzgerald Stadium.

The Kingdom led 2-8 to 0-8 at the break in Killarney, with David Clifford and Paul Geaney scoring the goals for the hosts, the latter's coming just before half-time which proved crucial in changing the dynamic of the game.

With the All-Ireland Senior Football Championship now into straight knockout territory, eight-time All-Ireland winner Philly McMahon feels "consistency is key" in the race for Sam Maguire.

The former Dublin defender will watch his county take on Donegal at Croke Park on Sunday [13:15 BST] with a place in the quarter-finals up for grabs, and while they go in as underdogs, they face a side that has endured patch form in the championship.

Following a shock exit from the Ulsster Championship at the hands of Down, Jim McGuinness' men turned on the style in the All-Ireland SFC Round One game away to Kerry, only to be caught again on home turf in the next round by Cork.

The Dubs lost a Leinster final to Westmeath and then fell to Louth - whom they beat in a provincial semi-final - in the opening round of the All-Ireland series before bouncing back with victory over Cavan.

Between the provincial and All-Ireland championships, there are no undefeated teams .

For Donegal, pre-championship favourites, their up and down form has been something of a surprise, but McMahon feels the jeopardy of elimination may help them refocus.

"They are still a strong outfit with a lot of quality," McMahon told BBC Sport NI's Mark Sidebottom.

"They still went to Killarney and beat Kerry, so if they get past Dublin and a good draw in a quarter-final, they're still where they want to be.

"Their standards are still high. They are inconsistent but still know what works for them, so if they can iron out the issues and wheat's not working for them, they are still a danger and have nothing to fear.

"They've lost to teams who were underdogs, but have nobody to fear at the top table and maybe that is what they need in terms of motivation because the games they have lost, maybe they haven't got that."

Our final day of Round Three action gets under way on a glorious afternoon at Croke Park, where Donegal and Dublin battle for a place in the All-Ireland quarter-finals.

It's a fitting setting given that every remaining championship game will be played at GAA headquarters from next weekend onwards, offering both sides a chance to lay down an early marker on the sport's biggest stage.

The reward for victory is a quarter-final against either Cork, Galway, Louth or Tyrone, while defeat will bring an abrupt end to the summer.

Dublin arrive looking to improve on a disappointing home record in 2026, having won just once in six outings at Croke Park, while Donegal are seeking a response after last weekend's dramatic one-point defeat to Cork in Ballybofey.

The Tir Chonaill men were among the favourites for Sam Maguire at the start of the season and will be eager to avoid following Armagh out of the championship after the Orchard County's elimination by Kerry on Saturday.

Large pockets of Donegal supporters continue to stream into the stadium, joining a sizeable Dublin contingent as anticipation builds ahead of throw-in.

The stakes could hardly be higher.

Good afternoon and welcome to our coverage of today's games in Round Three of the All-Ireland Senior Football Championship.

Yesterday, Kerry laid down the gauntlet with a convincing win over Armagh to book their place in Monday's quarter-final draw, while Mayo get the better of Meath in Castlebar to join the Kingdom in the last eight.

First up today, we have Dublin hosting Donegal at Croke Park in a game between teams that have struggled for consistency this year.

The Dubs recovered from their Round One defeat by Louth to power past Cavan last week, but Donegal find themselves in the last chance saloon due to their one-point loss at home to Cork.

Can Jim McGuinness' men bounce back or has Ger Brennan's return to the Dublin sideline lit a fire under the boys in blue?

Later today, Clones is the venue as Monaghan welcome Leinster champions Westmeath.

The Farney produced the goods against Roscommon last week to keep their season alive, while Westmeath's fightback in Galway fell short as they are tasked with an additional hurdle to reach the quarter-finals.

This game has flown under the radar a little, but has all the ingredients to be a cracker.

Also, we will keep you updated on the latest from Thurles as Cork and Offaly take to Tom Semple's field for an All-Ireland hurling quarter-final.

Let's hope the action matches today's glorious weather, so stick with us and we will bring you all the latest.
