The Bafana Bafana keeper was sent off for two bookable offences – first for time-wasting and then for showing dissent at the decision – near the end of his side's 1-0 win over AmaZulu on Thursday night.
Khune later tweeted to the official account of the PSL, saying: “@OfficialPSL but I did nothing wrong.u guys need to take action against this poor referees.
“Its about time action is taken against this referees by @OfficialPSL. They've been very poor since beginning of the season.
“Its unfair how we are painted bad for our actions on de field but we are provoked by these referees, can call me names but I stand 4 what's right.”

However, Khune has now taken to Instagram to apologise.
"To the football fraternity, my Family,Friends,Teammates and Fans. No words can validate my careless statements on social media yesterday. All I have now are apologies for my choice of words which were not appropriate," he said.
