Davy Burke will review his and Roscommon's preparation after a last-gasp loss to Kildare cost them home advantage in next weekend's All-Ireland SFC preliminary quarter-finals.
Kevin Feely kicked a superb 74th-minute winner from an attacking mark near the right touchline to clinch a 1-16 to 1-15 victory that saw Kildare leapfrog Roscommon into second spot in Group 3.
It means Roscommon will be back on the road on Saturday against either Cork, Donegal or Galway.
"We're very down to be honest," Roscommon manager Burke told RTÉ Sport. "The game was there to be won and we couldn’t clinch it. It's very disappointing."

Roscommon trailed by five points after 15 minutes but got back into the contest when Kildare were reduced to 13 due to black cards for Alex Beirne and Ryan Houlihan, and Enda Smith’s goal helped Burke’s side into a 1-06 to 1-04 lead at the interval.
"We took advantage of the extra men and kicked 1-03 unanswered but we started very slowly, Kildare were well on top," said Burke.
"You can see their physicality, they probably got those cards because of their overexuberance. They were really up for it and we were flat.
"I have to look and my preparation and the team’s preparation because Kildare were mad for road today and we weren’t.
"We were happy enough [at half-time] after the slow start. We came out and kept them to two points, going point for point. Ultimately they saw it out better and fair play to them."
Roscommon goalscorer Enda Smith believes his side can regroup ahead of next weekend
Burke named an unchanged side for Sunday’s game but is considering major changes ahead of next weekend after an energy-sapping contest with his native county.
"Maybe that’s something else we need to look at, I think we need to freshen things up now," he said.
"We've a six-day turnaround and you could see both teams flagging badly in that heat."
Burke’s counterpart Glenn Ryan said his players were under pressure to produce a performance after their below-par showings against Sligo and Dublin.
The Lilywhites’ aerial power proved the difference against Roscommon. They scored five points from attacking marks, including three from match-winner Feely.
"We knew Roscommon were going in with huge momentum behind them and it was going to take a bigger effort than what we produced so far," said Ryan. "Not that there was a lack of effort, we just hadn’t produced what we had hoped.
"You could play a challenge match and if you win by a point you’re happy. That's what’s inside us, we’re all in this game to try and win things. Whether it’s a point or ten points, you’re hugely satisfied.
"For those players, who have had questions asked of them, when you see the effort they put in... I wouldn’t deny the criticism but I'd say what they put in during the week, they’re not getting out of their performances. You’ve a savage bunch of fellas in there."
Ben McCormack, who scored three points from play, said Kildare ignored the critics after the defeat to Dublin and thrived on being underdogs against Roscommon.
"The few weeks leading up to it, we weren’t showing our true selves," he said. "We had two hard weeks’ training and a few hard words to each other. We all knuckled down, we knew this was a big one. We had something to prove to everyone, but especially ourselves. We just kept it tight and dug in.
"It plays in our favour, coming in as underdogs. We'd rather it like that instead of being hyped up. We'd rather no-one was talking, and just come in and play the game."
