Tyrone are capable. In Malachy O'Rourke, they have a manager who knows how to win. Dublin are definitely capable of beating anybody and I wouldn't be surprised if they went on to win the All-Ireland.

But are they the same force that they once were? I don't see it, and the game may hinge on the fitness of Con O'Callaghan. Dublin are a different team when he's playing. He looked laboured against Derry and I wasn't tremendously surprised that he wasn't fit enough to come on against Cork.

It'll be a big ask for him to play this weekend at the level we're used to seeing him play. For Dublin to have any chance this year, they'll need Con back and I don't know his current fitness status.

One change to each of the Tyrone and Dublin teams named midweek.

Peter Harte will replace Mark Bradley in the Tyrone forwards.

Brian O'Leary will replace Lorcan O'Dell at corner forward for Dublin.

So that means Dublin captain Con O'Callaghan will not start.

This appears to be the one of the four games this weekend that no pundit, supporter or casual observer can definitively call with any degree of certainty.

There's plenty of history between these two at Croker with Tyrone dominating the noughties while the Dubs have firmly held the upper hand in more recent meetings.

Malachy O'Rourke is forced into one change to his Tyrone team which hammered Cavan to top their group and book passage to the last eight.

Michael McKernan misses out entirely with a shoulder injury picked up early in that game and is replaced by Mark Bradley. That's not a like for like switch with Kieran McGeary reverting to the half-back line allowing Bradley to take his place in the forwards.

Two of Tyrone's 2024 All-Ireland U'20 stars make the bench in Michael Rafferty and Shea O'Hare along with this years U'20 footballer of the year Eoin McElholm.

O'Rourke also has the likes of Conor Meyler, Ruairi Canavan and Peter Harte to call upon from the bench.

For Dublin - a large portion of their success may depend on the fitness of Con O'Callaghan who has struggled with a hamstring problem picked up in their first group game at Galway.

The Cuala attacker didn't feature at all in their win over Cork here at Croke Park seven days ago but is once again named on the bench.

Dessie Farrell has named the same starting team which dealt with Cork with the only change amongst the replacements with Eoghan O'Donnell replacing Brian O'Leary.

It's also worth noting that there is no Colm Basquel on the Dublin panel for today.

Tyrone: Niall Morgan; Cormac Quinn, Padraig Hampsey, Niall Devlin; Peter Teague, Rory Brennan, Kieran McGeary; Brian Kennedy, Conn Kilpatrick; Seanie O'Donnell, Mattie Donnelly, Ciaran Daly; Darren McCurry, Mark Bradley, Darragh Canavan.

Subs: Oisin O'Kane, Aidan Clarke, Michael Rafferty, Frank Burns, Shea O'Hare, Ben McDonnell, Michael O'Neill, Peter Harte, Conor Meyler, Ruairi Canavan, Eoin McElholm.
