Footage has emerged of Sonny Bill Williams' monster brawl in an SG Ball clash with the South Sydney Rabbitohs back in 2003.

News that Sonny Bill Williams could be returning to the Canterbury Bulldogs have been trashed by NRL360 host Paul Kent.

A WWOS report earlier today said the player who started his career at the club before sensationally walking out for a career in French rugby in 2008 could make a comeback to the NRL.

The report said the club has started “informal talks” with the Auckland Blues star.

Now 33, Williams is looking to finish his All Blacks career with another Rugby World Cup later this year.

But NRL360 host Paul Kent has rubbished the report.

“It got reported on nine.com.au but it’s totally false, I don’t know where that’s come from,” Kent said.

“If Sonny Bill — I’m not even going to make a stupid bloody suggestion — it’s impossible. I’d like to see him come back because then I could put my book back on the shelf and hopefully sell a few more. Other than that, it’s not going to happen.”

Kent is referring to his book Sonny Ball which he said people could find “down the bottom of the $2 bin at bargain basements”.

Williams returned from rugby union in 2013 to win a premiership with the Sydney Roosters before returning to union.

The 33-year-old star was due to present jerseys to Bulldogs players before their season opening game against the Warriors last week but was overcome by the Christchurch terror attacks.

A proud Muslim, Williams posted a video following the attacks and has since promised to travel to Christchurch to raise money for the community.

There may also be an option for Williams to play in Canada with the Toronto Wolfpack reportedly trying to lure the star.

The club tabled a $5 million deal to sign Williams last month.

“We are working towards making Sonny Bill Williams a Wolfpack player for 2020. We would love to have him join the Wolfpack family and we will pay whatever it takes to make that happen,” Wolfpack owner David Argyle said last month.

“The excitement he would bring to the sport of rugby league in this country would be incredible.”

Williams spoke to the Sydney Morning Herald late last year and said the door wasn’t closed on a return to the game that launched his career.

“I’m not sure if league is in my future at 33,” he said at the time. “If there are offers, I will examine it with my family and go from there.

“I still have the fire inside me. I still feel fresh.”
