Referees' chief Keith Hackett insists Graham Poll will not resign on Sunday.
Poll failed to keep count of the cards shown to Josip Simunic
Reports had circulated that Sunday's game between Portsmouth and Arsenal would be the Tring official's last.
Hackett, general manager of the Professional Game Match Officials Limited, says Poll, 43, will still be in action before the season ends.
But he would not confirm Poll will carry on next season, saying: "It's not his last game on Sunday, he has other games we will line him up for."
Hackett says Poll will at least be in charge of a play-off semi-final after the weekend.
The PGMOL general manager also said Poll had not handed in his notice, which would be mandatory before he could stand down.
Hackett said: "This is pure speculation. We have the play-offs coming up and he is officiating in the play-offs.
"He is an employee of the PGMOL and has it within his contract to give us a period of notice, and that has not been forthcoming."
It was my error and the buck stops with me
Graham Poll, resigning after his World Cup howler
Hackett, though, admitted he is unsure of Poll's intentions for next season.
He said: "I don't know, contract negotiations with all referees will commence at the end of the season.
"We will sit down with Graham and all our referees and discuss these issues in the close season."
Poll rose to become one of English football's top referees, and has often been chosen to officiate high profile games.
He has been England's representative in the 2000 European Championships, and at the 2002 and 2006 World Cups.
His international career came to a controversial end when he failed to dismiss Croatia defender Josip Simunic after showing him a second yellow card in the game against Australia, and only sent him off after showing him a third.
Poll was pointedly not selected to referee in the second round of matches, and tendered his own resignation from international football soon after the World Cup.
In tendering his resignation, he admitted his error and said: "The referee takes responsibility for his actions on the field of play. I was the referee that evening. It was my error and the buck stops with me."
