Warriors skipper Roger Tuivasa-Sheck set to sign with the Blues

Roger Tuivasa-Sheck's transition from rugby league to rugby in time for the 2019 World Cup is reportedly all but complete.

The Warriors and Kiwis fullback will sign on with New Zealand Rugby and likely join the Blues for the 2019 Super Rugby campaign, according to Radio New Zealand, putting himself in the frame for an All Blacks World Cup call-up.

The Samoan-born livewire played both rugby and rugby league throughout high school before linking up with the Sydney Roosters in late 2011.

He has since gone on to earn a big-money move to the Warriors and become club captain, leading them to 13th place in the 2017 NRL season.

He is yet to inform his Warriors teammates of the alleged move, RNZ reported.

Australian media reports in October - around the time of the Kiwis' disastrous Rugby League World Cup campaign - suggested that Tuivasa-Sheck had long-held ambitions to play the 15-a-side game and crack the All Blacks.

At the time, Tuivasa-Sheck kept quiet on the speculation.

Yet, should he switch from league to rugby, he may have a fairly difficult time earning a black jumper amidst a crowded back-three field.

He'll have little time to earn the trust of coach Steve Hansen before the 2019 World Cup, while a score of prodigious backs - including Rieko Ioane, Damian

McKenzie and Jordie Barrett - will play protagonists' roles in 2023.

Other players could also emerge in the meantime - but Hansen didn't mind the idea of having Tuivasa-Sheck at his disposal.

"I like the rumour," Hansen told reporters in October.

"If he comes over to rugby he'd be a good player, I think - one of the (Super Rugby) franchises, it'd be quite handy to pick him up."
