Matthews was appointed for his administrative expertise, having been on the PSL executive committee for the past five years, as well as for the sterling work he did with SuperSport United over the past 12 years.
But allegations of his mistreatment of staff within the PSL offices have led to calls for his head with members having been asked to submit affidavits regarding a meeting where Matthews allegedly used abusive language.
Matthews reportedly confronted Sipho Mandla, who works in the finance department, for not wearing a tie on a Friday.
But he has denied using abusive language and telling staff that his child was more competent than some of them.
Matthews has since told The New Age: "I've only been a CEO for just a few weeks, therefore it would be wrong to say that knives are out for me.
"However, the PSL executive committee will meet next week Thursday to study the report.
"I am happy that the staff members are submitting their version of events, because this will bring out the actual truth and stop speculation and misinformation.
"But it's an internal matter and this is as far as I'm prepared to comment."
