Holland boss Bert van Marwijk will have to wait until tomorrow to find out whether Arjen Robben will be fit for the World Cup.
The Bayern Munich winger came on as a half-time substitute in yesterday's 6-1 thrashing of Hungary and scored two goals before being forced off with a hamstring injury five minutes from time.
The 26-year-old remained in Holland for scans when the rest of the team flew to South Africa.
It was expected the results of the scans would be revealed today but the Dutch FA (KNVB) have tonight admitted they will not be released until tomorrow.
The initial fear was that Robben would not be able to play in the finals and Van Marwijk is concerned he will be deprived of arguably his most creative player.
"I would rather have lost the game and still be able to take Arjen," he said.
"He felt a sharp sting and that does not bode well.
But I have not yet lost hope."
Team-mate Robin van Persie admits it is the worst thing that could have happened to the squad.
He said: "Everybody was shocked. This is a bit of a doomsday scenario. I find it unbelievable.
Everyone was down afterwards."
Holland's first game is on June 14 against Denmark, while they also face Japan and Cameroon.
