FitzSimons - now a Sydney Morning Herald columnist and prominent broadcaster – gave Folau a spray on Nine's Sports Sunday television show.
He was incensed at Folau's assertion that he wanted an apology from Rugby Australia (RA) and an admission that they were wrong to sack him for posting on Instagram that homosexuals, among others, were headed for hell unless they repented.
FitzSimons' outburst was unleashed during his Sports Sunday appearance.
"Camera one on me," he said. Israel Folau and your demand for an apology… mate, bring it in tight.
