The semi-final losers in the four provinces enter the qualifier race across a weekend where eight more teams will exit the championship.
Remember all games must be decided on the day: if teams are level after 70 minutes there will be two periods of ten minutes extra-time, followed by two more of five if necessary, and, finally, a free-taking competition.

Monaghan not where they want to be
The plaudits that came after the win over Tyrone were many in a game that delighted the purists. Put aside all the "well aren't they punching above their weight for such a small county" blather and it was accepted that Monaghan's graph would continue to rise as the summer progressed.
Fermanagh were expected to provide another test in the Ulster semi, but Malachy O'Rourke's men surely would have enough to book a final berth. The test duly came, but the Farney were never in full flow. Behind for much of the encounter, they eventually got their noses in front down the final stretch, before Eoin Donnelly's sucker punch broke their collective hearts.
Last year, it was Down who pulled the rug out beneath a Monaghan side who we all thought were on a sound footing to take on Tyrone for the Anglo Celt trophy. A year earlier, Longford surprised them through the back door. Such setbacks, seismic in nature, have taken some of the gloss off the good work done by O'Rourke since his arrival in 2012.
Reaching the Super 8s will ease some of this summer's pain, but this month began with high hopes that Monaghan would finally break through the ceiling and reach the last four in the Sam Maguire race.
And now they head to Fraher Field for a first ever meeting with Waterford in the championship. The Déise's win over Wexford was one of the highlights in Round 1, where manager Tom McGlinchey was keen afterwards to allow his troops celebrate.
He told RTÉ Sport: "The thing about us is we don't do media bans and we don't do drink bans. We're definitely going to enjoy tonight."
On the road again for Mayo
It's a trip to Tipp for Stephen Rochford and co. After their facile win over Limerick, Liam Kearns' side are expected to give the Green and Red a stiffer examination as part of their desire to atone for a limp performance against Cork in the Munster semi-final.
Much was expected of the Premier this year, with some even tipping them to reach the Super 8s. Their collapse against the Rebels left Kearns in a rather exasperated state. The four weeks that have passed should have focused the Tipperary minds.
Mayo learned very little in their demolition job on Shannonside. Of concern, perhaps, was the concession of three goals, but that aside we're still somewhat in the dark as to whether the Connacht men are ready for another long haul.
Lee Keegan, Brendan Harrison and Diarmuid O'Connor should all play some part in Thurles and indeed there seems to be growing calls that Keegan should be deployed in midfield.
Previous championship clashes
2016 Mayo 2-13 Tipperary 0-14 (All-Ireland semi-final)
2002 Mayo 0-21 Tipperary 1-14 (2002 All-Ireland qualifiers)
1922 Tipperary 1-5 Mayo 1-0 (All-Ireland semi-final)
1919 Tipperary 2-2 Mayo 1-4 (All-Ireland semi-final)
Will it be pretty?
The view is that defences will be to the fore when Carlow host Tyrone. Having spoken to Carlow fans after their loss to Laois, there was much disappointment that the side opted in the main for a defensive counter-attacking approach.
Eight points was their grand total a fortnight ago and that won't win you much, even though the Barrowsiders did miss a few goal chances
Turlough O'Brien won't care what I or others think and we can expect Carlow to try and frustrate Tyrone.
A fortnight ago, Mickey Harte's men survived by the skin of their teeth against Meath.
The Red Hand required a Cathal McShane point in the sixth minute of injury-time to force the extra period and Harry Loughran's 76th minute goal ultimately propelled them through.
They hit 14 wides in normal time and racked up half a dozen goal chances that they didn't take, allowing Meath to almost pull off an upset win.
Niall Morgan comes back into goals in place of Michael O'Neill, while Cathal McCarron starts in the full-back line ahead of Hugh Pat McGeary, who drops to the bench.
Peter Harte missed the drama in Navan due to suspension, but he slots into the half-back line in place of Tiernan McCann, who was issued a straight red card against Royals following an off the ball incident.
Meanwhile, Declan McClure is named to replace Padraig McNulty in midfield, where he will partner up with Colm Cavanagh.
Carlow and Tyrone meet in the championship for the first time.
Provincial derbies, remembering 2002 and more....
Cavan manager Mattie McGleenan targeted a productive run through the back door following the defeat to Donegal. The road to redemption saw them sweep Wicklow aside and now they host Down not Kingspan Breffni, but at Brewster Park, owing to pitch redevelopment at the Cavan town venue.
The Mourne County, in the words of our reporter Francis Mooney "failed to push their game anywhere near the realms of championship intensity" against Donegal and you wonder what shape, mentally, are they in to trouble Cavan.
This will be their first meeting in the championship between the sides for eleven years. Their most recent competitive meeting was in this year’s Allianz League Division 2 in March when Cavan won by 0-17 to 0-14 on their home patch.
Longford can take some crumbs of comfort from their loss to Dublin and now must prepare for the visit of Kildare. The Lilywhites got back on track with an eight-point defeat of Derry on 9 June.
The question is can they push on?
In his preview on RTÉ Radio's Morning Ireland, Tomás Ó Se said: "we don't have a clue what we'll get from Kildare. They have great potential, but there is also a great unpredictability about them. I give Longford a great chance here."
They last met in the championship in 2015 when Kildare won a qualifier tie by 19 points. That was their first championship clash since 2003, having gone 20 years prior to that without meeting.
Last 5 Championship Meetings
2015 Kildare 2-24 Longford 0-11 (All-Ireland qualifiers)
2003 Kildare 1-14 Longford 2-6 (Leinster quarter-final)
1983 Kildare 3-9 Longford 2-9 (Leinster quarter-final)
1974 Kildare 2-10 Longford 0-11 (Leinster quarter-final)
1973 Kildare 0-13 Longford 0-8 (Leinster quarter-final)
Armagh navigated the backdoor route to reach an All-Ireland quarter-final last year. A solid victory over Westmeath a fortnight ago gave hope that they can jump a few more hoops this summer.
They'll head to Sligo in confident to face opposition who got a bit of a thumping from Galway at the start of the month.
They meet in the championship for the third time, their previous meetings coming in the 2002 All-Ireland quarter-final. They drew (Armagh 2-9 Sligo 0-15) in Croke Park, with Armagh winning the replay by 1-16 to 0-17 in Navan. The Orchard later went on to win the All-Ireland for the first time.
A case of what might have been for the Yeats County.
Elsewhere, Leitrim welcome Louth to Carrick-on-Shannon. The Wee County finally got their first win of 2018 when they comfortably saw off London in Round 1.
Their only previous championship meeting was in the 2015 All-Ireland qualifiers when Louth won a Round 1 clash by 1-16 to 0-11 in Drogheda.
It's a third championship clash for this pair, with Offaly having won the previous two. They triumphed by 2-18 to 1-18 after extra-time in Tullamore in the 2010 qualifiers and by 1-12 to 1-08 in the 2003 qualifiers in Ennis
Saturday will be a dry and bright summer's day. Variable high cloud will make the sunshine a little hazy at times. Highest temperatures of 17 to 23 degrees, coolest in western parts of Connacht and Ulster. Light winds with afternoon sea breezes. A similar day on Sunday, with temperatures rising a degree or so.
