The International Cricket Council will reveal the number of teams that will compete at the next World Cup on Monday, it has been confirmed.
A meeting of the ICC's executive board will take place in Mumbai with the number of participants set to be reduced from 14 to 10 for the 2015 tournament in Australia and New Zealand.
The format of the World Cup has been criticised for being too long, with India's success in the 2011 final arriving six weeks after they opened the tournament against Bangladesh.
A reduction in the number of competing teams is likely to see the number of associate members reduced after teams such as Canada and Kenya were on the wrong end of some heavy defeats.
"The length of 50 overs will find certain teams out but I think there are 10 teams that can seriously compete in that format," Lorgat told Sky Sports News.
"That's a debate we are still finalising; in fact the board meeting over the next two days will consider that and will determine which teams will play in the 2015 World Cup."
The ICC currently has 10 full member nations with Zimbabwe the only of those whom is not currently a Test-playing country.
There may, however, be scope for at least one of the associate nations to play in the tournament with the ICC still yet to reveal how qualification would take place.
While the associate nations struggled at the recent tournament Ireland proved their ability to compete with the full members, highlighted by victory over England.
The Irish also reached the Super Eight stage in 2007 when they memorably beat Pakistan.
