Warriors halfback Blake Green.

A bout of stomach flu has hit the Warriors this week, sidelining three frontline stars as they prepare for Friday night's crucial match against the Gold Coast Titans.

Key spine members Blake Green, Issac Luke and Karl Lawton have all been struck down by the bug and now face a race to be declared fit, with the Warriors flying out for the Gold Coast on Wednesday morning.  

Kearney said while the trio are no certainties to take the field at Cbus Super Stadium, early indications are that the impacts of the bug won't be long lasting.

"We will have to see how they pull up over the next little period," Kearney said.

"We are pretty hopeful, the doctor reckons it's a 24-hour thing, so we will have to see how they pull up.

"It better be quick because we are jumping on a plane in the morning.

"I'm pretty confident that they will be OK… there's a bit going around, it's that time of the year."

Tohu Harris was the other high-profile absentee at Tuesday's field session, with the veteran back-rower rested due to another flare up of the knee injury he has been carrying since the Anzac Day loss to the Melbourne Storm.

While Harris is expected to play through the injury for his club, Kearney all but confirmed it will keep him out of the upcoming Kiwis v Mate Ma'a Tonga clash in Auckland.

"We are just managing his load. He tweaked his knee in the Melbourne game and then [again] leading into the Dragons game," Kearney said.

"Since then it's been managing the situation, but I anticipate he is going to be OK [for Friday].

"He's already spoken to Madge [Kiwis coach Michael Maguire] about his situation and was upfront and honest with Madge.

"In the last four weeks we have probably seen him out on the field maybe four or so times, he hasn't been out here often.

"In preparation for a big game like that… it's a challenge, and I know him and Madge have spoken."

Hooker Nathaniel Roache took part in limited training on Tuesday for the first time since he suffered a corked muscle in his back during last month's Magic Round, while Jazz Tevaga (ankle) and Patrick Herbert (quad) both got through running work.

Having lost back-to-back games against the Broncos and Storm, the Warriors are languishing in 13th position and desperately need a result against the Titans, in what will be forward Adam Blair's 300th Telstra Premiership game.

Despite the disruptions caused by key personnel missing practice, captain Roger Tuivasa-Sheck said he didn't expect it would have an impact on the squad come game day.

"It happens and it is part of the every day, every job has it," Tuivasa-Sheck said.

"Those [sick] boys will get the videos sent to them, they will watch training and they'll do what they need to do.

"Come captain's run whoever turns up to do the job will get it done. Everyone is a professional player here [and] they just need to turn up and get the job done."
