bet365 cut Holland from 10/1 into 9/1 during the 6-1 rout against Hungary on Saturday - but then pushed them back out after seeing Arjen Robben limp from the field.
The Bayern Munich winger, on as a substitute, sustained a hamstring injury five minutes from time and, despite the results of his scan not being available until Sunday, coach Bert van Marwijk was very downbeat.
And so are Bet365.
Spokesman Steve Freeth said: "Holland are the value alternative to the likes of Spain and Brazil and weight of money during the Hungary game forced us to go 9/1 from 10/1.
"However, Arjen Robben limping off could be bad news for Dutch backers and we've gone back to 10/1 until the picture becomes clearer."
