Match Tied (Royal Challengers Bangalore win one-over eliminator)
Three former Sri Lankan players are the subject of an investigation by the International Cricket Council's Anti-Corruption Unit.
Sri Lanka Cricket confirmed the development on Wednesday, insisting that no current players were involved in the alleged wrongdoing.
The board was responding to reports in the media inferred from the comments made by Sports Minister Dullas Alahapperuma, who had hinted that active players were being investigated by the ICC for match-fixing.
"What the honourable minister actually mentioned was about an investigation launched by the ICC Anti-Corruption Unit against three former Sri Lanka players and not the current national players," SLC said in a statement.
The ICC has refused to share details regarding the ongoing corruption probe.
Sri Lanka introduced tough measures last year in order to deal with the menace of illegal betting and match-fixing or spot-fixing in the sport.
Cricket in the country has been plagued with accusations of widespread graft in recent years with an Al Jazeera documentary suggesting that a 2018 Test against England was marred by match-fixing.
New laws in the island nation bans people with family links to gambling businesses from taking part in the functioning of SLC and carries a jail sentence of 10 years for fixing convicts.
Former Sports Minister Harin Fernando had reportedly claimed cricket in Sri Lanka was riddled with graft and that the ICC considered the board to be one of the world's most corrupt organisations.
Legendary opening batsman Sanath Jayasuriya was charged under the ICC anti-corruption code in October 2018 for failing to cooperate with the authorities in a match-fixing probe. Former pacer Nuwan Zoysa, another high-profile figure in the country's cricket structure, was suspended over a graver offence relating to fixing.
