Sonny Bill Williams has reportedly refused to wear the logo of a Super League sponsor, due to his religious beliefs.
Williams, 34, joined the newly promoted Toronto Wolfpack last year, returning to rugby league after the All Blacks' unsuccessful Rugby World Cup campaign.
However, despite the Super League having signed away both sponsorship and naming rights to gambling agency Betfred, Williams will not wear the company's logo on his playing jersey, club chairman Bob Hunter told the Daily Telegraph.
"We're in discussions with Super League about this, but Sonny has been very clear in his stance on the matter," Hunter said.
"I think Betfred will benefit by taking the position that we respect and honour the players' religious beliefs.
"In today's society there are some very sensitive issues but I think the sponsor can say, 'Yes, okay, we understand this. He's a big brand and big name but we get it.'"
Williams is no stranger to boycotting sponsors on his playing jersey, covering up BNZ's logo during his time playing for the Blues in 2017.
In both cases, the sponsor logos conflicted with Williams' Muslim faith, objecting to both banking interest as well as gambling.
