Wessels issued a statement through his lawyers on Friday angrily denying the accusation against him, made by two players from his own squad.
"I emphatically deny the incident took place or that I ever uttered any words remotely approximating the words that I am accused of uttering," Wessels said.
The no-nonsense attitude that characterised Wessels's 20-year playing career continued with a threat by him to bring charges of racism against his accusers, saying that such counter action would be "necessary and fair."
Details of the incident have become clearer since Wessels's lawyers obtained a sworn affidavit from the white cricketer to whom Wessels is alleged to have made a racist remark about two black players.
The Eastern Province Herald newspaper said on Friday that Wessels is alleged to have told Johann Louw at a net practice on October 23: "Stop talking nonsense to those two animals, I want you to bowl now."
Louw was with team players Lyall Meyer and Deon Carolus at the time.
Louw, however, has provided Wessels's legal team with a sworn affidavit saying "the incident never took place," according to the newspaper.
The initial complaint against Wessels was made to the Eastern Province Cricket Union by the chairman of club side Gelvandale, who Meyer and Carolus play for.
