Manly are unlikely to risk injured trio Jamie Lyon, Shane Rodney and Brett Stewart in next weekend's NRL trial match against the Warriors in New Zealand.

The club will find out the seriousness of Jamie Lyon's strained ankle ligaments on Wednesday but they are prepared to give him as much rest as possible before their season-opener against Melbourne on March 12.

Coach Des Hasler said Lyon, who injured the troublesome ankle in the first half of Saturday's NRL All Stars clash on the Gold Coast, was not in doubt for round one.

In better news for the club, cult hero George Rose will not miss any football despite suffering a broken nose in the All Stars game.

"(Lyon) is fine, he only twisted the ankle and George is already back training so he's OK," Hasler told AAP.

"We'll see (whether Lyon will play against New Zealand), it's something we'll look at and we're not in any rush, but we're certainly not going to be risking anyone in that game."

Rodney and Stewart, who are both coming off knee injuries that ended their seasons in 2010, are progressing as expected and Hasler was "hopeful" that both would take their places against Melbourne - though neither should feature in the New Zealand fixture on February 26.

"(Stewart's) injury is progressing really well, he had a run (on Tuesday morning)," Hasler said.

"We're just going to have to keep monitoring that, that's going to come down to a battery of tests and medical feedback on that. We won't know until we get closer to the event.

"Shane is a tremendous professional ... He works very hard at his injuries and he is on track at this stage to possibly (be ready for round one)."

The Sea Eagles will also be without suspended duo Steve Matai and Glenn Stewart, although the latter will be eligible to play Melbourne after serving the last of his four-game ban in the Warriors trial.

Against the Warriors, Hasler will be looking for a similarly consistent effort to that which he saw in Manly's 18-0 victory over Cronulla on Saturday.

It was a three-try victory over a team which narrowly escaped the wooden spoon last season, but Hasler was heartened by what he saw.

"I particularly liked the way we controlled the game, I thought the first 40 minutes we controlled the ball really well and got through what we needed to do, we built pressure and maintained possession," he said.
