Saracens and England No 8 Billy Vunipola was drawn into the issue when he "liked" Folau's post and then made a statement of his own backing his rival - he will have to meet the RFU to explain his position.
"A spokesperson for Channel 4 has said that "(Bully Vunipola)'s views are incompatible with our values as an inclusive broadcaster and in light of this Billy Vunipola won't be used as a contributor in Channel 4's rugby coverage".
The Waratahs have stood down under-fire fullback Israel Folau until further notice, after his anti-gay posts on social media.
Vunipola has been named on the bench for Saracens' Gallagher Premiership match against Bristol on Saturday and travels to Ashton Gate knowing his club are to launch an internal enquiry into comments that are odds with their stance on diversity. We want to make it clear that he does not speak for the game with his recent social media posts.
The grey area could leave RA needing to pay out Folau's full four-year contract through to the end of the 2022 season in a similar train wreck situation to the one that had Quade Cooper paid out his full $600,000 contract for the Queensland Reds last year despite being exiled to play in Brisbane's club rugby competition.
Earlier that day a TV news crew from 9 News spotted Folau having breakfast at a cafe with his wife, Rugby Union Players' Association boss Prataal Raj and an unknown person.
Houston tweeted that Folau's "way is not the right way", after the Wallabies star doubled down on his harmful rhetoric by sharing a meme informing the masses that hell awaited "drunks, homosexuals, adulterers, liars, fornicators, thieves, atheists and idolaters".
Folau met RA chief executive Raelene Castle on Friday, with neither party backing down in a feud that has threatened to turn ugly.
His rugby career looks finished but former Wallabies and Brumbies five-eighth Rod Kafer said his likely absence would benefit Australia's national side.
"That's another tradition that is man-made and we always have to go back to what the Bible says about what He (God) says", Folau said in his address. "I don't HATE anyone neither do I think I'm ideal", the Saracens back row said.
An Australian television news channel questioned Folau on the street after the meeting.
Publishing on Instagram, Folau said "hell awaits" homosexuals "unless they repent".
In an apparent show of support to his fellow Christian, Vunipola states that "Man was made for woman to pro create that was the goal no?"
"Absolutely [I'd walk away]", Folau said. I'm not ideal I'm at least everything on that list at least at one point in my life.
Folau's chances of switching back to rugby league in Australia were also dashed late on Thursday with the governing body, the Australian Rugby League Commission (ARLC), ruling out any return to the sport.
"First and foremost, I live for God now".
