Khumalo’s performance came under scrutiny after Chippa lodged a formal complaint with both the Premier Soccer League (PSL) and SAFA, questioning his decision-making during the fixture.
The Chilli Boys further accused the referee of being biased in much of the second half after awarding Sekhukhune two penalties – one converted, the other missed by striker Bradley Grobler.
The match, played at the Peter Mokaba Stadium last week, ended 1-1.
In their submission, Chippa did not contest the legitimacy of the second penalty but argued that several of Khumalo’s calls unfairly benefited their opponents.
SAFA’s review committee meets weekly to examine officiating and identify clear, match-influencing errors before making recommendations to head of referees Abdul Ebrahim.
Following deliberations, it is understood Khumalo was found to have erred in his application of the laws of the game.
While an official ruling is yet to be communicated, sanctions range from a six-week suspension to demotion to the lower leagues, both financially punitive given the higher stipend for topflight matches.
Chippa, still fuming, also asked the PSL to guide them on “proper channels” to escalate the matter to the SA Police Service.
However, only SAFA has jurisdiction over referees, appointing officials for both the elite division and the Motsepe Foundation Championship.
