Singapore - Baseball and softball will not feature in the 2012 London Olympics, after they were wiped from the programme in a vote on Friday.
The two sports failed to win a majority of votes in a ballot of members at the International Olympic Committee Session in Singapore.
The 26 other sports from the Athens 2004 programme did win a majority of votes and will remain on the programme in London.
"Needless to say, these sports will be disappointed," IOC president Jacques Rogge said.
"But this does not disqualify them for ever."
"Olympic sports they are in Beijing, and Olympic sports they will remain. As such they will remain eligible for the Olympic programme after 2012."
The sports programme for 2016 will be voted on after the 2008 Beijing Games.
Once again all sports will be put to a vote one-by-one.
Baseball and softball's ejection opens the door for two of golf, squash, karate, rugby sevens and roller sports to be added.
The IOC's Executive Board will propose two from the five and members will vote on their inclusion on Saturday.
