Former Pakistan leg-spinner Danish Kaneria was urged to "come clean" after the England and Wales Cricket Board (ECB) rejected his appeal against a life ban from cricket at a hearing in London on Tuesday.
The ECB handed down the life ban last year after a panel found him guilty of inducing his then Essex team-mate Mervyn Westfield to deliberately under-perform.
He got him to agree to concede a certain number of runs in return for money while bowling in a county one-day match in 2009.
After Tuesday's verdict, ECB chairman Giles Clarke, called who was also chairman of the International Cricket Council's Pakistan task force from 2010-2012, called on Kaneria to make a clean breast of the matter.
"It is high time that Mr Kaneria came clean about his involvement in these corrupt activities and stopped misleading the Pakistan cricket fans and wider public with his empty protestations of innocence."
Although imposed by the ECB, the now 32-year-old Kaneria's ban was effectively a worldwide sanction: boards under ICC jurisdiction have agreed to uphold punishments imposed by individual countries in such circumstances.
The scandal broke in 2010 when police in Essex, England, arrested both Kaneria and Westfield. However, the Pakistani was released without charge and has maintained his innocence throughout.
Legal proceedings against Westfield continued however. He spent two months in prison and the ECB banned him for five years from first-class cricket and for three from recreational cricket.
Although the ECB panel upheld Kaneria's ban in full it chose to 'vary' the sanction imposed on Westfield.
It ruled he could return to club cricket on April 1 next year, provided he took part in a "stringent" anti-corruption programme organised by England's Professional Cricketers' Association.
Kaneria has now seen two appeals against ECB charges fail after a CDC panel dismissed his case in April.
