STORY: The original plan was for the opening ceremony to be held before Qatar's game on Nov. 21 against Ecuador -- which created the unusual situation of two matches being held before the ceremony.
Normally the ceremony is conducted before the kick-off of the first game of the tournament.
The Group A match between Senegal v Netherlands and the Group B match between England and Iran were scheduled to take place before the ceremony on the Monday.
The plan has to be voted on by the heads of FIFA's six regional confederations and president Gianni Infantino but, despite the late notice, is expected to win support.
The switch to a Nov. 20 opening ceremony and game would allow the Senegal-Netherlands match, scheduled for 1300 local time on Nov. 21, to kick off later in the day. The Group B matches on that day, which also include the United States v Wales, would be unaffected.
Another source close to the proposal said the switch could be confirmed as early as Thursday and that the plan was to ensure that fans did not have to pay for any changes to flights or accommodation.
People living in Qatar told Reuters on Wednesday that they were supportive of the idea as it will allow the Qatar national team - and the country - to get more of the spotlight when the tournament begins.
