The 2022 World Cup tournament is expected to commence on Sunday, November 20, instead of November 21, 2022.
Host Qatar and Ecuador will also be opening the tournament with their game in place of the Senegal and Netherlands game.
Initially, the Qatar vs Ecuador game was fixed as the third match in the Group A opener.
The changes proposed follows a request from South American confederation Conmebol to Qatar and Ecuador indicating that it fits in with the tradition of either the hosts or the holders being involved in the opening match.
It is yet to be decided if the changes suggested would be implemented.
The final decision will be made by the bureau of the Fifa council, which comprises the six confederation presidents, plus Fifa president Gianni Infantino.
If it is approved as expected, it would not change the release dates for players, and Senegal against the Netherlands would be switched to 16:00 on the Monday, given only three games would be played instead of the present four.
England’s Group B match with Iran, which is being played at 13:00 on 21 November, would be unaffected, as would Wales’ opening match against the United States of America at 21:00 on the same date.
