According to FIFA, Mbokazi has been charged due to an incident described as "Misconduct of players and officials, unsporting behaviour towards an opponent or a person other than a match official."
That is enforced by Article 14, Article 14.1.b of the FIFA Disciplinary Code.
That has attracted a R108,000 fine on Mbokazi and a one-match ban, and he served that suspension by not featuring in Bafana's final qualifying match against Rwanda.
Zimbabwe forward Knowledge Musona has also received similar punishment from the world football governing body after being red-carded in the same match.
