Kerry's early salvo suggested they might blow Tyrone away with their pace but things have changed rather quickly with the Kingdom now becoming somewhat rattled by the Red Hands' tenacious tackling. Still early days of course.

Ronan McNamee is in nosebleed territory but the defender sends over a lovely point to move Tyrone two clear after 15 minutes.

This has plenty of bite, which is keeping things interesting in the middle of the park.

Both teams have vented their frustration at referee David Coldrick, and we're seeing a few frustrated tackles coming in.

It was the same with the hurling final last week, but it's so, so good to have fans back at Croke Park.

They're living every score, kick and hit - and we're going with them!

It's evident when Michael McKernan sends it over for the Red Hands and the roar immediately goes up around Dublin.

Tyrone lead after 12 minutes.

Just like Harte at the other end, O'Shea breaks free and levels the game once more. There was half a goal chance but he kept it safe and sent it over the bar.

Anything Tyrone can do, and all that...

Three on the bounce from the Ulster champions as Peter Harte breaks free from his marker before sending it over. Nicely done.

Mattie Donnelly calls the mark and sends the ball over the black spot.

We're level once more!

Niall Morgan splits the posts with a nicely-taken 45. That should settle any Tyrone nerves.

Moments earlier Sean O'Shea had a goal chance blocked by Frank Burns. Tyrone need to be careful the aren't carved open by this fluid Kerry attack.

The Kingdom are looking to exploit the wide open Croke Park turf but Tyrone are standing their ground and making things difficult.

However with one opportunity, Clifford calls the mark and slots over his second score of the game.

David Clifford has taken just 20 seconds to open his account for the afternoon.

That's an ominous start from the favourites.

Kerry win the throw-in and immediately look to attack.

It's nearly time for us to get underway.

It's a glorious afternoon at Croke Park and you'd have to say we have be perfect conditions for a game of football.

With Kerry already favourites you have to wonder if Feargal Logan and Brian Dooher were doing a rain dance last night to try and spice conditions up at the home of GAA.

Time will tell...

Former Kerry captain Darran O'Sullivan believes Tyrone will try and frustrate the Kingdom in today's semi-final.

Tyrone joint-manager Feargal Logan has said the Covid-19 outbreak in his squad ahead of today's game has been "a concern".

Some famous faces get behind the men in green and gold.

There was disappointment for Tyrone earlier in the day as their minor side fell just short against Meath in the All-Ireland decider at Croke Park, losing by 1-12 to 1-11.

Cormac Devlin's goal helped Tyrone lead 1-3 to 0-2 but Oisin O Murchu's superb finish got Meath on terms before they moved 1-7 to 1-6 ahead by half-time.

Meath extended their lead to 1-11 to 1-8 but Tyrone fought back to level deep in injury-time as Conor Owens pointed.

A Shaun Leonard point restored Meath's lead before Owens agonisingly missed a free chance to ensure extra-time.

After all the upheaval caused to the Tyrone squad by their Covid crisis, their starting line-up for today's game shows just one change in personnel from the side which started the narrow Ulster Final win over Monaghan.

Frank Burns is drafted into the half-backs as Mark Bradley drops out of the starting line-up with Kieran McGeary named in the half-back line and Niall Sludden switching to the number 12 shirt.

In the team announced earlier today, Tiernan McCann was named at right half-back but a late change now sees Burns coming into the side and he looks likely to operate as a sweeper.

Cathal McShane remains on the bench after not looking particularly sharp after his second-half introduction against Monaghan.

After naming an unchanged team from the Munster Final hammering of Cork, Kerry have also just announced a late change as Darragh Moynihan is drafted in to replace Diarmuid O'Connor in the half-forwards.

Brian Dooher, a man who knows a thing or two about winning an All-Ireland, believes Kerry are favourites not only for the semi-final, but for the overall title even before Mayo's stunning victory over Dublin.

"Kerry are favourites for the All-Ireland and they were favourites before Dublin were even put out of the championship," he said.

"We've experienced how good Kerry are. We saw that in Killarney when we were overwhelmed by them.

"We don't underestimate the challenge we have ahead of us. We definitely have it all to do.

"But we'll do the best we can and we'll see where that takes us. If it's good enough, it's good enough. If it's not good enough we'll have to go back again and look at things."

For the first time since 2015, Dublin's name won't be on the Sam Maguire.

Mayo secured a stunning 0-17 to 0-14 extra-time All-Ireland Football semi-final victory which ended the Dubs' six-year reign as champions.

Dublin looked in total control in the first half as they led 0-9 to 0-2 and still were 0-10 to 0-5 up at the break.

But after their dismal first half, Mayo summoned up an astonishing revival as keeper Rob Hennelly's late 45 levelled the contest at 0-13 to 0-13.

As the Dubs continued to wilt, Mayo pulled clear to win in extra-time.

The Connacht champions, without an All-Ireland title since 1951 and having lost 10 finals since that victory, will face either Kerry or Tyrone in the decider and their semi-final win should give James Horan's men the confidence to end 'the Mayo curse'.
