Crunch time at Croker
It's the Croke Park round of the Super 8s, meaning all the counties get the opportunity to strut their stuff at HQ.
Of course Dublin and Cork already did so last week, the Jones Road's venue also serving as the champions' nominated home ground, despite efforts at Congress to prevent such a scenario.
Cork will be equal parts heartened and sickened by last weekend's result. They matched the Dubs throughout before being hit with three goals in the final 10 minutes.
The Rebels created plenty of their own goal chances, and took two of them, but how will they fare against a team that has reverted to massed defence following some costly concessions against Donegal? It's hard to see the average of 2.75 goals per game so far not taking a dip.
Ronan McCarthy makes one change, Killian O'Hanlon returning from injury to replace veteran Paul Kerrigan. Sean Powter is on the bench after overcoming a hamstring injury.
Tyrone have racked up 1-37 and conceded just 0-20 in their last two games (Cavan and Roscommon) and are a slick counter-attacking machine.
Mickey Harte's men beat Cork by 16 points in the qualifiers last year and will be confident of a victory that would ensure their semi-final spot, if not by the same margin against improved opposition.
Cork: Mark White; James Loughrey, Thomas Clancy, Kevin Flahive; Liam O'Donovan, Tomas Clancy, Mattie Taylor; Ian Maguire, Killian O’Hanlon; Kevin O’Driscoll, Sean White, Ruairi Deane; Mark Collins, Brian Hurley, Luke Connolly
Tomás O Sé's verdict
"It's a knockout match for Cork and Tyrone don't want to need a win against Dublin so it's huge for both teams.
"Cork surprised a lot of people last week with their style of play - they went man on man and went at Dublin. They were direct, aggressive and pushed Dublin's buttons for a long while. The end score did not reflect their performance in any way.
"Thirteen in defence for Tyrone, Cork's ability to hit huge scores. It's a huge match in the making but I worry for Cork that Tyrone will blockade that scoreboard for them and sneak it."
Dublin juggernaut rolls on
Can anyone stop the Dubs' remorseless march to five in a row? At this stage, you would expect the proposition won't be seriously tested until at least the semi-finals.
Cork gave Jim Gavin's men a game last week but they still won by 13 points - 5-18 to 1-17.
A 20th successive Championship victory (since drawing with Mayo in the 2016 final) would ensure qualification for the last four with a game to spare for a second year in a row.
Dublin beat the Rossies by 14 in Croker at this stage last year and halving that margin would be an achievement for Anthony Cunningham's side tomorrow.
Roscommon won't face the same deep-lying defence that limited them to 0-13 against Tyrone in Hyde Park last week but Dublin would expect to score more than the 0-17 the Red Hand managed, even if their opponents reach for the comfort of a blanket.
The Connacht champions are the only team remaining in contention for Sam Maguire that have yet to concede a goal and they will need to maintain that record to have the chance of pulling off what would be a huge upset.
Diarmuid Connolly could make a first appearance in almost 18 months after his surprise return to the Dublin panel.
Tomás O Sé's verdict
"A scary one for Roscommon. They were deprived of space and time on the ball against Tyrone and managed 13 points but no goals.
"Dublin are brilliant one on one. John Small snuffed out Ruairí Deane, Cork's best player last week. On the other side, they have the ability to raise it and tag on scores.
"I would question the Roscommon defence even though they will load up.
"Cian O'Sullivan and Philly McMahon don't inspire confidence in terms of man-on-man marking but the Dubs are only cranking it up at this stage and they'll have plenty for Roscommon."
