Cricket's world governing body said Wednesday players would be briefed about the risk of approaches from "corrupters" during England's upcoming tour of Sri Lanka amid fears of match-fixing.

The International Cricket Council's anti-corruption chief Alex Marshall said Sri Lanka was the subject of corruption inquiries but the England tour itself was not under question.

"However, I will take the opportunity to brief both the teams over the coming days to ensure they remain alert to the risks from would be corrupters," Marshall said in a statement.

TV news channel Al Jazeera broadcast a documentary in May showing a groundsman and a player allegedly discussing possibilities of altering the pitch at Galle where England will play their first Test against the hosts from November 6.

England will play five one-day internationals, three Tests and a one-off T20 between October 10 and November 27.

Galle groundsman Tharanga Indika and professional cricketer Tharindu Mendis allegedly speculated about fixing the pitch to ensure a result in under four days in the Test against England.

Both men have been suspended by Sri Lanka Cricket, pending the outcome of an ICC investigation. A third man, provincial coach Jeevantha Kulathunga, was also suspended.

Marshall said ICC investigators were currently in Sri Lanka , but declined to elaborate.

"I can confirm that we have, at their request, provided a detailed briefing to the Sri Lankan President, Prime Minister and Sports Minister," Marshall said.

Sri Lankan players and umpires have been accused of match-fixing in the past.

Jayananda Warnaweera, a former curator at Galle, was suspended by the ICC for refusing to cooperate with a corruption inquiry. His three-year ban ends in January.

No big-name Sri Lankan player has ever been convicted of corruption but several stars have alleged match-fixing and spot-fixing.

Sports Minister Faiszer Musthapha promised tougher laws and a special police unit to deal with match-fixing after the Al Jazeera documentary made sweeping allegations of corruption.

He said existing laws were inadequate to deal with match-fixing and other forms of cheating.
