A number of Olympic sports will debut in 2028. One will not be back.

Earlier this century, the International Olympic Committee changed the way sports could be introduced into the Games. Along with the 28 “core” sports that are contested every four years, the local organizers of each Olympics are allowed to include up to five additional sports on a temporary basis to better reflect local flavor at each Games or to recognize a sport that’s growing in popularity.

Thus, we now have an ever-changing roster of Olympic sports. With the Paris Games complete, here’s a look at what will be dropped from the program for the 2028 Los Angeles Olympics and what will be added.

Leaving: Breaking

Raygun, we hardly knew you.

After its first-time inclusion in the program for the Paris Olympics, breaking will not be on the roster four years from now in Los Angeles, even though it was first practiced in the United States.

“It’s up to each local organizing committee to determine which (additional) sports to put forward that fit with their vision of the Games,” IOC Sports Director Kit McConnell said last year after Los Angeles Olympic organizers declined to include breaking. “Obviously breaking fit very clearly with Paris’s vision of a very youth-focused urban engagement.”

Nonetheless, the World DanceSport Federation — breaking’s global governing body — has said it will push to get the competition included on the docket for the 2032 Games in Brisbane, Australia.

Rejoining: Baseball and softball

Between 1900 and 1984, baseball made only sporadic appearances at the Olympics, and then only as a demonstration or exhibition sport. It finally made the official Olympics roster for the 1992 Barcelona Games and appeared in five straight Olympics, only for the IOC to vote it and softball out again in 2005, starting after the 2008 Olympics, for a few reasons: Major League Baseball would not allow its players to compete, MLB’s drug-testing rules were less strict than the IOC’s and the feeling that baseball and softball were too American.

Since the last time baseball and softball were considered official Olympic sports at the 2008 Beijing Games, the sports have returned only once in Tokyo three years ago as optional sports chosen by the local organizing committee. But they’ll be back on the program in 2028, on a temporary basis.

Rejoining: Cricket

Cricket was included on the Olympic roster just once, in 1900 when only two teams — Britain and host France, fielding a team composed mainly of British expatriates — competed. Since then, cricket’s various governing bodies have opposed the sport’s Olympic inclusion, though those feelings changed as the years wore on, and soon there was a push to include the sport on a temporary basis in Los Angeles. The IOC accepted the proposal, in part to increase the Olympics’ popularity (and get a better TV deal) in India, the world’s most populous nation where cricket is king.

Cricket will employ its Twenty 20 or T20 version for men and women at the 2028 Games, with each team getting one inning each and matches lasting about 3½ hours.

Joining: Flag football

The thought of full-fledged American football, with pads and hitting, in the Olympics remains preposterous, but the IOC said last year that there are “approximately 20 million flag football players across over 100 countries.” Thus, we will see this version of the sport — where instead of tackling, defenders attempt to remove flags attached to the ballcarrier — in Los Angeles. The competition, for men and women, will feature five-on-five games played on 50-yard fields, with no linemen.

Rejoining: Lacrosse

Lacrosse was an official Olympic sport in 1904 and 1908, though only three teams competed in the former and only two in the latter. It has since returned three times on a demonstration basis, but not since 1948.

In 2028, men’s and women’s teams will compete using the lacrosse sixes format, with each team using six players — as opposed to 10 in field lacrosse — and games played on a smaller field. Faceoffs occur only at the start of each quarter, with goaltenders restarting play after a goal is scored against them, and all competitors play both offense and defense (as opposed to field lacrosse, where four players from each team must remain in the defensive zone and three must remain in the offensive zone at all times).

Joining: Squash

Squash has been included at other continental sporting events, such as the Asian Games, Pan American Games and Commonwealth Games, and it will make its Olympic debut in Los Angeles. The racquetball-like sport has never been included in any form on an Olympic roster.

Top squash tournaments often are played at temporary venues, which was seen as a plus because of the Olympic edict to make the Games more sustainable.

Slightly changing: Modern pentathlon

Modern pentathlon was in danger of dropping off the Olympic program over worries that the sport — a five-event competition featuring fencing, swimming, horse riding, shooting and a cross-country run — was outdated. It was saved from the chopping block, though the horse-riding element will be replaced in Los Angeles with an obstacle competition, akin to something you might see on “American Ninja Warrior.”

Still up in the air: Boxing

An Olympic sport at nearly every Games since 1912, boxing has yet to be approved for the 2028 roster. Last year, the IOC stopped recognizing the International Boxing Association — which oversaw the sport at the Games — because of questions about its governance and reforms. For the sport to return in Los Angeles, the IOC would need to approve a new governing body for the sport. World Boxing hopes to become that governing body, but the IOC has yet to approve it.

“We want to see boxing on the program in L.A. Now it is up to the boxing community to organize themselves for the sport and for the athletes,” IOC spokesman Mark Adams said in Paris this month.
