FIFA has dropped proposals which would have seen the 2022 World Cup expanded to have 48 teams.
The tournament currently involves 32 teams, with the final qualifying teams whittled down from more than 200 eligible countries.
However, a proposal had been floated that would see an extra 16 teams take part in the World Cup by involving other neighbouring host countries.
Both FIFA and 2022 host Qatar had carried out a feasibility study to see if that could happen.
However, they've now decided to drop the proposal due to 'current circumstances'.
Relations between Qatar and some of its neighbouring Gulf states are poor, with countries such as Saudi Arabia and United Arab Emirates having severed diplomatic relations with the state.
World Cup organisers also looked at the possibility of Qatar itself hosting an expanded tournament, which would require FIFA to lower some of the usual stadium and facility requirements for host countries.
In a statement, FIFA said: "A joint analysis, in this respect, concluded that due to the advanced stage of preparations and the need for a detailed assessment of the potential logistical impact on the host country, more time would be required and a decision could not be taken before the deadline of June.
"It was therefore decided not to further pursue this option."
World Cup 2022 is due to take place in November and December, in a bid to avoid the intense summer heat that would impact the tournament if it was held in the traditional timeframe.
The 2022 tournament has proven controversial, with particular concerns having been raised over the treatment of migrant workers building facilities for the tournament.
