Sonny Bill Williams

Nurmagomedov is in Australia on a promotional tour, telling fans how he become one of the biggest names in sport during a live Q&A session at Olympic Park.

Williams posted photos of himself and Nurmagomedov on Twitter and Instagram, one of them where he was on stage with the reigning UFC lightweight champion.

"Alhamdulillah. Blessed to meet & share the stage with the brother @khabib_nurmagomedov May the most high continue to bless your journey," Williams wrote.

Earlier this month, Newstalk ZB presenter Heather du Plessis-Allan told her listeners it was not worth the expense of sending the PM to the Pacific Islands Forum in Nauru.

"The Pacific Islands wants money from us," she said.

"The Pacific Islands don't matter. They are nothing but leeches on us."

Her comments were posted on social media, prompting lots of angry reactions and some abusive and offensive putdowns of the broadcaster herself.

All Blacks centre Williams announced on Tuesday that he will fight Laundy the weekend after the All Blacks' Test against Italy.

New Zealand coach Steve Hansen has already given the green light for Williams for his next bout, saying the fight would be a low-key affair.

“I think he’s just going to get off the plane and do it. It’s the sort of athlete he is,” he said.

"We've got guys boxing all the time, as part of their training. Again, my understanding of the fight is that it's more of an exhibition fight I think than a go down and knock yourself out fight.

Williams aggravated an old knee injury this week and Blues medical staff said an x-ray yesterday showed a loose piece of bone in his knee joint.

He will undergo keyhole surgery later today in Auckland.

Blues medical staff expect that the second five-eighth will be unable to train for approximately four weeks.

The 32-year-old was due to assemble with the All Blacks squad next week to prepare for the first test against France - an update of his involvement from All Blacks management will be given on Monday.

The twice World Cup winner posted a photograph on his Twitter page with his left forearm and hand encased in a plaster cast.

The Blues say Williams would be out for between six and eight weeks.

The 32-year-old could return in time for the clash against the defending champion Canterbury Crusaders on May 19, two weeks before the All Blacks play their first match in their three-test series against France in Auckland.

The Blues, who have a bye this week, play South Africa's Sharks next Saturday at Eden Park.

The 32-year-old Williams' playing future has been the subject of intense speculation virtually every year since he walked out on a five-year contract with rugby league's Canterbury Bulldogs in 2008 to play union in France.

Williams was forced into clarifying his future after a former Sydney Roosters player told an Australian radio station at the weekend that he would join the club in August after the Auckland Blues' season ended.

"I love being a part of the Blues Rugby team & All Blacks," Williams wrote on his Twitter account on Monday.

The Blues second-five is rumoured to be returning to the NRL with the Roosters at the end of the Super Rugby season.

Former Roosters player Jimmy Smith made the comments on Australian radio.

"The mail is good," Smith told the Big Sports Weekend radio programme on Sydney radio station 2KY.

"From what I understand, the deal is done. It will be a short stint at the end of the Super Rugby season."

Smith told the Big Sports Weekend on Sunday that the backrower will be back in Bondi before the finals with the Super Rugby final set for August 4.

"I feel he'll stay in rugby," Mundine, a former NRL player turned professional boxer, said.

"As great as rugby league is, rugby is the world game. Lots of countries play it all over Europe and South Africa, it's massive. I went to South Africa to watch him play a [Super Rugby] game and they had fans waiting outside the hotel room. It's a big thing. It's the biggest sport over there. It's crazy."

The experienced 44-test midfielder spoke for the first time following the Stade de France encounter, won 38-18 by the All Blacks, in Edinburgh on Thursday evening after the team naming for Saturday's (Sunday NZ time) clash against Scotland.

Williams took his brain-explosion play on the chin, after being yellow-carded and also conceding a penalty try when he batted away a French cross-kick in-goal, instead of attempting to catch the ball.

The play he made is standard in his former sport of rugby league, but not allowed in rugby.

Under-fire All Black Sonny Bill Williams has received some welcome backing after his Stade de France brain fade.

All Blacks coach Steve Hansen has gone in to bat for his embattled second five-eighth after he was widely lambasted for his knucklehead play early in the second half against France that saw him sinbinned, coughed up a penalty try and was the catalyst for the French to roar back from 31-5 to 31-18.
