An early wide from David Clifford - unusually from him, too.

He'd have expected to open the scoring there.

Here we go. The match is underway at Croke Park and there was an early scare for Tyrone.

Oisin McConville believes Tyrone's huge All-Ireland Football quarter-final with Kerry today could need a penalty shootout to decide the outcome.

Asked for his prediction on BBC Sounds' The GAA Social, the Armagh great said he "reluctantly" gave the vote to the defending All-Ireland champions.

"The reason I say reluctantly is I don't know," said McConville.

Three-time Tyrone All-Ireland winner Brian McGuigan previewed today's game on Newsline last night. Here's what he said:

“Kerry is the benchmark of county football. We grew up looking up to them.

“Any time we drew Kerry we treated them with respect but we didn’t fear them. We left that legacy for the current crop of players to have the same feeling going into a match.

“They were tough games against brilliant teams and these current teams are both great teams.

“Tyrone seem to be coming good at the right time. The Tyrone players are coming into form.

“It’s going to be a great game. A lot of our scores might come from deep but we have the two Canavans and Darren McCurry up front so they’re going to take a bit of watching.”

While the new All-Ireland Senior Football Championship format came in for some criticism during the early round-robin games, GAA president Larry McCarthy has said this year's format has "worked very well".

"The format has worked very well. Maybe the lack of jeopardy early on but the fact that three teams came out of every group meant that on the last day, everybody was playing for something," McCarthy told BBC Sport NI.

"If we didn't have that format, there'd have been an awful lot of dead-rubbers and we wanted to eliminate that.

"We've developed a system which I think delivers that."

When Kerry travelled to Omagh to face Tyrone in Division One earlier this year, we tracked David Clifford's every move and asked Kingdom supporters for their thoughts on the 2022 Footballer of the Year.

Michael Murphy on GAAGO:

I think it's back to David Clifford, Paudie Clifford and Sean O'Shea. I think it's those three players that have to win the game for Kerry at the moment.

I'm very interested to see what Tyrone are going to do with them today.

Big championship days out against Kerry in Croke Park have given Tyrone some of their greatest memories.

2023?

Not to get Tyrone fans overly excited or anything, but Tyrone wins over Kerry in the championship are always followed by All-Ireland titles (2003, 2005, 2008 and 2021).

Ahead of this afternoon’s opener, join us in reliving the 2005 and 2008 All-Ireland finals between Kerry and Tyrone.

The GAA has confirmed that the draw for the semi-finals will take place on Sunday evening - if one is required that is.

If Tyrone beat Kerry today and Derry beat Cork tomorrow, a draw won't be required because Tyrone and Derry have both already played Armagh and Monaghan in the championship.

If Tyrone and Derry both win, they would face each other in the semi-finals, with the other semi-final being the winner of winner of Armagh/Monaghan v winner of Dublin/Mayo.

Also, if Kerry, Cork & Mayo all win, a repeat pairing can’t be avoided, so all four teams would be drawn from the same bowl. The first team out would play the second team, and the third team would play the fourth.

Here are the repeat pairings to be avoided: Kerry v Cork, Kerry v Mayo, Cork v Mayo, Tyrone v Armagh, Tyrone v Monaghan, Armagh v Derry and Monaghan v Derry.

The semi-finals are scheduled to take place at Croke Park on 15 and 16 July.

Kerry have named a full-strength team for today's quarter-final with Paul Geaney and Gavin White returning to the line-up after recovering from injury, replacing Mike Breen and Tony Brosnan.

Tyrone stick with the same 15 that started last week's preliminary quarter-final win over Donegal in Ballybofey.

As ever, the match-ups between these two sides will be fascinating. If the 2021 semi-final is anything to go by, Ronan McNamee and Conor Meyler will be expected to pick up David and Paudie Clifford respectively.

At the other end, it could be Jason Foley up against Tyrone sharpshooter Darren McCurry, who's been in excellent form this season.

But of course, there will be captivating one-on-one battles across the field. Tyrone got their match-ups spot-on two years ago - can they repeat the trick today?

Kerry: Shane Ryan; Graham O'Sullivan, Jason Foley, Tom O'Sullivan; Paul Murphy, Tadhg Morley, Gavin White; Diarmuid O'Connor, Jack Barry; Dara Moynihan, Sean O'Shea, Adrian Spillane; Paudie Clifford, David Clifford, Paul Geaney.

Subs: Shane Murphy, Tony Brosnan, Mike Breen, Brian O Beaglaioch, Barry Dan O'Sullivan, Ruairi Murphy, Micheal Burns, Stephen O'Brien, Donal O'Sullivan, Dylan Casey, Sean O'Brien.

Tyrone: Niall Morgan; Michael McKernan, Ronan McNamee, Padraig Hampsey; Cormac Quinn, Michael O’Neill, Peter Harte; Brian Kennedy, Conn Kilpatrick; Conor Meyler, Ruairi Canavan, Kieran McGeary; Darren McCurry, Matthew Donnelly, Darragh Canavan.

Subs: Lorcan Quinn, Frank Burns, Aidan Clarke, Niall Devlin, Richard Donnelly, Niall Kelly, Nathan McCarron, Cathal McShane, Sean O'Donnell, Joe Oguz, Niall Sludden.

Referee: Brendan Cawley (Kildare)

From the All-Ireland final of 1986 to that epic semi-final two years ago, the Kerry-Tyrone rivalry is tense to say the least.

It may have taken them a long time to face each other in the championship – the GAA was 102 years old when that 1986 decider took place – but the the two counties have certainly made up for lost time ever since.

This afternoon’s quarter-final will be the ninth time the teams have met in the competition, with the current head-to-head tally sitting four apiece. Could be more nicely poised, could it?

John Haughey takes a look back at how this rivalry has played out down the years.
