The inclusion of boxing at the Los Angeles 2028 Olympics have been "put on hold" after Monday's 141st session meeting of the International Olympic Committee.
The IOC said that the issue surrounds the governing of the sport with the committee withdrawing their recognition of the the International Boxing Association (IBA) in June with another governing body yet to be recognised.
Boxing is Ireland's most successful Olympic sport with 18 of their 35 medals coming in that discipline.
Meanwhile five sports, including cricket and flag football, proposed for inclusion at the LA Games were officially approved.
Organisers said this week they wanted cricket, flag football, lacrosse, squash and baseball-softball added to the event.
Irish Squash have welcomed the move, something they described as "monumental" for their sport.
"This news is particularly exciting for Irish squash and our crop of talented budding stars and is sure to inspire more youngsters across the island of Ireland to join their local club and try their hand at squash," said Irish Squash chief executive Scott Graham.
"This is a momentous day for squash players worldwide. Now is the time to believe in our big dreams of competing on the Olympics world stage," added president Rosie Barry.
Each host city, under IOC rules approved a few years ago, can request the inclusion of several sports for their edition of the Games.
For baseball and softball, cricket and lacrosse it will be a return to the Olympic Games, while flag football and squash will be making their debut .
"Their inclusion will allow the Olympic Movement to engage with new athlete and fan communities in the US and globally," said IOC president Thomas Bach.
Cricket is set for an Olympic return after appearing once at the 1900 Games.
The Los Angeles Games proposal is for a six-team Twenty20 tournament for men and women.
The IOC board also recommended the inclusion of modern pentathlon, after the international federation replaced horse riding with an obstacle running course following a scandal at the Tokyo 2021 Olympics.
Weightlifting also secured its Olympic spot for Los Angeles after changes were made to its anti-doping testing procedures, among other things.
Both sports had been provisionally left out of the LA Games.
While all five new sports' inclusion is only for one edition of the Games, they are banking on the boost provided by Olympic participation to spur growth as they look to remain an attractive Olympic product going into the next four-year cycle.
Flag football is a non-contact format of American football played by teams of five.
Baseball was featured in several previous Games. It was added to the 2020 Tokyo program after being left off in 2012 and 2016, but it will not be a part of the Paris Games.
Softball, the female counterpart to baseball, has appeared at five previous editions of the Summer Games and was also left off the Paris agenda.
