Peadar Mogan restores the Donegal lead but it could have been a goal as a slip at the other end from Aidan O'Shea prompts a quick counter and Mogan was put through only to thump over.

Monaghan topped Group Three and progressed straight to the quarter-finals after their four-point win against Down at the Athletic Grounds earlier today.

That result sees the Mournemen progress to the preliminary quarter-finals in second place.

Eoin McElholm says Tyrone "should always be pushing" for All-Ireland titles but insists manager Malachy O'Rourke is keeping the team grounded ahead of their pivotal Group One game against Cavan.

The Red Hands have been talked about as All-Ireland contenders after securing an impressive win over Ulster champions Donegal in Ballybofey, but McElholm says the players are paying no heed to outside noise.

"That's what Malachy's good at, keeping us grounded," said McElholm, who is fresh off being named the Under-20 Footballer of the Year after helping his county secure back-to-back All-Ireland crowns at the grade.

"Obviously Tyrone always should be All-Ireland contenders, just for such a good footballing county and the amount of quality in the team.

"We should always be pushing for an All-Ireland and people are going to say we're all All-Ireland contenders, but Malachy has pushed us right down to Earth and says 'you're as good as your last game', so hopefully we can put up a good performance on Sunday."

On Saturday, Shane Walsh was the Galway hero as his ninth point of the game with the final kick saw his side edge Armagh by 2-22 to 0-27 in a thriller at Breffni Park.

Heading into the game, Armagh knew they were straight through to the quarter-finals as winners of Group Four, but Galway's continued interest in the All-Ireland Senior Football Championship was far from secure.

Those prospects looked bleak at the end of the first half when they trailed by eight, having been outplayed with two penalties in the process.

But they roared back into it after the break with goals from John Maher and Rob Finnerty injecting life as they grabbed the win which ultimately saw them claim third place in the group, which means they hit the road next week for a preliminary quarter-final.

Paddy Tally believes his Derry side are "not that far away" from beating the top teams despite exiting the All-Ireland in the group stages.

Saturday's 0-22 to 0-20 defeat by Dublin left Tally's side bottom of a hotly-contested Group Four.

Their sole point came from a draw with Galway, but Tally believes the narrow defeat in Newry by Dublin shows his side are on the right track.

"We didn't plan this to be the last day of the season," Tally told BBC Sport NI.

"The team were starting to go really well and we looked in better shape than we've been in for a while, but we hit a good Dublin team today."

Group Four had been billed as the 'group of death' with reigning All-Ireland champions Armagh, beaten finalists Galway and 2023 winners Dublin drawn with the Oak Leafers.

Derry were also pitted against eventual winners Donegal in the preliminary quarter-final of the Ulster Championship.

Tally admits that made for a "difficult" first year in charge, but says the strong performances against Division One opposition will only fuel the belief his team belong at the top table of gaelic football.

"Everything that fell for us was really difficult this year, but that will build character.

"These boys will understand it, not that it will help because they believe they are good enough and they are good enough.

"I think they have realised that we're not that far away. It's going to take a really big effort to get back up there next season again."

Earlier today, Wicklow progressed to the semi-finals of the Tailteann Cup with a late one-point win against Westmeath.

Limerick take on Wexford in Sunday's other quarter-final that is about to get under way.

After falling to defeat to Mayo last time out, Tyrone manager Malachy O'Rourke has has made two changes to the side for Sunday's crunch Group One clash with Cavan in the All-Ireland SFC.

Brian Kennedy returns from injury and will start at midfield taking the place of Ben McDonnell. Padraig Hampsey will also start for Tyrone in place of Nathan McCarron who will now wear the number 14 jersey with Mark Bradley ruled out entirely.

Also named on the bench for the Red Hands is Eoin McElholm who this week was selected as the U20 Player of the Year, following Tyrone's All-Ireland success at the grade.

For Cavan, manager Raymond Galligan makes two changes to the team that was swept aside by Donegal in their second outing of the competition.

Ryan Donohoe and Sean McEvoy drop out with Oisin Brady and Paddy Lynch returning to action.

Today's referee is Paddy Neilan from Roscommon.

A huge roar greets both teams at a thronged and quite balmy Dr Hyde Park in Roscommon where Donegal and Mayo are set for one of this afternoon's crunch battles in Group One.

There has been a massive crowd in long before the teams emerged and the supporters are still streaming in.

By 6pm, both of these teams may still be in the championship, but there is also a very real prospect the year is over for the defeated.

Ulster champions Donegal comfortably hold the most superior scoring difference (+16), thanks to their 19-point victory over Cavan in round two.

However, the first tie-breaker is head-to-head, and given that Tyrone beat Donegal in the first round, the Red Hands will top the group if they beat Cavan and Donegal overcome Mayo, a sequence which would eliminate the Connacht county.

Tyrone will also finish top if they win and Donegal and Mayo play out a draw, which would knock Cavan out.

Courtesy of their win over Tyrone last time out, Mayo will top the group if they beat Donegal and Tyrone defeat Cavan. This would eliminate Cavan.

Donegal will top the group if they beat Mayo and Cavan get the better of Tyrone, thus sending the Red Hands out. Jim McGuinness' Donegal will also secure first place if they win and the Tyrone-Cavan game ends in a draw, eliminating Mayo.

Both games ending in a draw is a highly unlikely occurrence, but if that does happen, Donegal will top the group on scoring difference while Cavan will finish bottom.

Mayo will finish top if they beat Donegal and Tyrone beat Cavan. They will also finish top with victory over Donegal and a draw in the Tyrone-Cavan game.

Cavan can still finish top despite entering the weekend bottom. To do that, they will need to beat Tyrone and hope that Mayo see off Donegal, which would eliminate Donegal. If Cavan win and Donegal-Mayo ends in a draw, Cavan will finish at the summit and Tyrone will head for the exit door.

Still with us?

Daire O Baoill had been selected to start ahead of Caolan McColgan, but in a late change, that has ben reversed
