Cricket South Africa has banned former international Gulam Bodi for 20 years after he admitted charges of contriving or attempting to fix matches in the 2015 Ram Slam T20.
He was charged with several counts of contriving or attempting to fix matches last month after an investigation conducted by CSA's Anti-Corruption and Security Unit.
He is understood to have submitted his plea over the weekend. After doing so, Bodi's lawyer said they would wait to see if the CSA would accept it.
In effect, it appears he therefore admitted to guilt to some extent because a not guilty plea would not require any form of acceptance.
CSA chief executive Haroon Lorgat said: "CSA thoroughly considered all the relevant factors and determined that a lengthy ban was appropriate.
"Our attitude to corruption will always be one of zero tolerance.
"There is no doubt that Mr Bodi's actions have threatened the integrity and image of the game that we love and he must be handed a strong punishment.
"We have had many discussions with Mr Bodi and he accepts the folly of his actions."
Lorgat said investigators believed Bodi was caught in what he referred to as the "planning stage" as he looked to fix domestic matches in South Africa last year.
He also stressed the investigation is ongoing and could take "weeks, months or even years" to complete.
Lorgat added: "We are fortunate in this instance that several players rejected his approaches and, as a direct result of our integrity processes, which include CSA and SACA player education programmes, the matter was brought to light and meticulously investigated.
"There are no winners in this sort of ill-fated and unfortunate matter. However, all of us in the cricket community must learn from this experience and remain vigilant.
"We expect that that Mr Bodi himself will learn and will actively assist us in reminding players of the dangers of corrupt behaviour."
Indian-born Bodi, 37, played two one-day internationals and a Twenty20 game for South Africa in 2007.
The investigation into his conduct comes 16 years after the Hansie Cronje scandal, which saw the former South African Test captain banned from cricket for life.
