Belfast's Tommy McCarthy has missed out on a place in the London Olympics, while Adam Nolan has qualified.
McCarthy was up against Vladimir Cheles of Moldova in the 91kg heavyweight semi-final at the AIBA European Olympic Qualifying tournament in Trabzon.
McCarthy, fighting in red, narrowly lost the first two rounds 4-3, 4-3.
McCarthy gave his all in a bruising final round but lost that aswell 7-6 to go down 15-12 overall.
Earlier in the day Nolan from Enniscorthy, Co Wexford, secured his place at the Olympics.
The pugilist defeated Romanian Ionut Gheorghe 19-10 in the 69kg welterweight semi-finals.
Nolan won every round on a scoreline of 7/5, 8/3, 4/2 to secure the win, rarely looking like he was in serious danger.
Nolan will now meet Germany’s Patrick Wojcicki in Saturday’s welterweight final.
An emotional Nolan said afterwards that he had realised a lifetime ambition: "It’s just unbelievable, I can't believe it, I just can't believe it. It's a boyhood dream," said the Enniscorthy man, who works as a Garda in Bray.
Irish head coach Billy Walsh, who was working Ireland's corner today along with Zuar Antia, said they were thrilled with the win.
"It was a fantastic result. I know his family. They are big GAA people," said Walsh, a former Irish Olympian.
"It's massive for Wexford. He’s the second Wexford boxer ever to qualify for the Olympic Games, following after myself.
"It's nice to see someone else take up the mantle and hopefully do a lot better than I did."
Paddy Barnes went down 21-14 to Turkey's Ferhat Pehlivan in the 49kg flyweight semi-final. Barnes, however, has already secured his Olympic berth.
McCarthy, who has had a fine tournament in Trabzon, admitted that he was devastated by the defeat saying: “I just waited too long from the first round and it was too late. The last round I was trying to put the pressure on but I should have been doing that for the full three rounds.
“I’m just devastated, four years is a long wait, I’m gutted. At the end of the day, that’s what counts isn’t it? I can’t make any excuses, he done the job on the day and I didn’t.”
