The police, who took Gibbs' voice samples, said he will not earn an automatic let-off.
Gibbs had admitted to accepting money from disgraced former captain Hansie Cronje to score fewer than 20 runs against India in a one-dayer during a 2000 tour.
He subsequently scored 74 runs and said he had forgotten about the deal, but was suspended and fined by the South African authorities.
