Roger Tuivasa-Sheck runs at the Bulldogs defence before the New Zealand Warriors fullback suffered a knee injury during Saturday's NRL game at Wellington's Westpac Stadium.

New Zealand Warriors and Kiwis fullback Roger Tuivasa-Sheck has been ruled out for the remainder of the NRL season after scans confirmed one of the club's star recruits for 2016 suffered a serious knee injury against the Bulldogs on Saturday.

The club announced on Monday that Tuivasa-Sheck faced more than six months on the sideline after he ruptured the anterior cruciate ligament in his left knee during the Warriors 24-20 win at Westpac Stadium.

Tuivasa-Sheck was making just his seventh appearance for the Warriors following a high-profile switch from the Sydney Roosters.

The 22-year-old's injury is also a setback for Kiwis coach Stephen Kearney as Tuivasa-Sheck was an automatic selection for next month's Anzac Test in Newcastle on May 6.

"Roger is absolutely shattered and so is everyone around the club," said Warriors head coach Andrew McFadden.

"We had huge expectations about what he would bring to us this season and he was so excited about the role he had to play. He had settled in well developing his combinations and timing but now this. It's the cruel side of football – we've certainly had more than our share of bad luck.

"Roger will have surgery in about three weeks and faces a long recovery but we'll make sure he has plenty of support and care around him."

One of the Warriors attacking linchpins, Tuivasa-Sheck sustained the injury when tackled by Bulldogs centre Kerrod Holland in the ninth minute. He initially tried to play on - the knee was stabilised by strapping - but he was clearly hampered by the injury and headed to the sidelines less than 10 minutes later in a forlorn attempt to "run off" the knock by exercising on a pitch-side bike.

However, it was soon apparent Tuivasa-Sheck would not recover and he limped to the dressing room for further treatment.

Tuimoala Lolohea shapes as the Warriors long-term replacement at fullback after diverting there from five-eighth once Tuivasa-Sheck departed.

The 21-year-old might also be in the frame for the Kiwis line-up - he made his solitary test appearance for New Zealand against England in Hull last November, at halfback.

Penrith's Peta Hiku, who played in the halves when Shaun Johnson and Kieran Foran were ruled out of last year's post-season test series in England, is another candidate to replace Tuivasa Sheck.

Tuivasa-Sheck was still in the process of replicating the form his displayed for the Roosters - he was defensively vulnerable missing 13 tackles in the first seven rounds - and scored just one try, though it was the match-winner against his former club in Auckland earlier this month.
