Kenya and Sri Lanka have reacted angrily after the International Cricket Council was forced to dismiss a report that their World Cup game was being investigated by the sport's Anti-Corruption Unit (ACU).
Kenya caused the shock of the World Cup by beating Sri Lanka
Both teams said the allegation was an "insult".
Kenya caused the shock of the World Cup with a 53-run victory over the 1996 champions and Group B leaders on Monday.
A report on Thursday alleged that the ICC had requested a tape of the match for further scrutiny.
However, cricket's governing body later issued a statement clarifying that the ACU receives tapes of all matches, regardless of the result.
"It's an insult to this side," said Sri Lankan manager Ajit Jayasekera.
"The reason we lost was because we batted badly. It was a gettable total, and the batting let the side down.
"We vehemently deny this allegation. Just because we lost the match to a team like Kenya it is disgusting to be accused of match fixing. I am very annoyed."
Kenya Cricket Association chairman Jimmy Rayani added that his side had been hurt by the allegations.
"What is the point of having a World Cup if everybody knows the results of all the games?" he said.
"Don't insult us every time we beat a big team."
A spokesman for the ICC confirmed to the BBC Sport website that tapes are requested from all matches at the World Cup.
"The ACU have spoken to representatives of both teams to reassure them that normal procedures have been followed," he added.
