Kerry manager Peter Keane has said his county will have to "suck it up" after being hit with a knockout blow in Páirc Ui Chaoimh.
A stuttering Kerry performance came back to haunt Keane and his players as Mark Keane netted a goal in added-time of extra-time in the Munster Football Championship semi-finals.
With no backdoor this year, it leaves Kerry out of the equation after one game and ruing the mistakes of the day.
Cork now go on to face Tipperary in the final, meaning another year without the Sam Maguire Cup's return to the Kingdom.
Keane, still trying to absorb what had such occurred in the driving rain in the Rebel County, told RTÉ Sport: "Obviously there's no doubt about it, it's disappointing. But I suppose you have to congratulate Cork. They never let us get away.
"When you are hanging on like that, it is always dangerous for a goal and that is what happened to us. We are obviously disappointed.
"We'll just have to look at ourselves, really. We had plenty of opportunities and just didn't put them away. Ball-retention and maybe a little bit of game-management towards the end [was lacking]. That is just something we have to go and learn from.
"We were two up and had chances to go further up, if not mind the ball."
Keane had yet to speak to his players when giving his thoughts on the events, but said he will "have a chat" with the players to reflect on the game.
He concluded: "It happens and it happened us, so we just have to suck it up, get on with it and congratulate Cork and wish them well for the rest of the year."
