"He’s out for probably one to two weeks from the medical opinion. We’ll just hope and wait it’s only the one, but it may be a couple," Stuart said.
"He’s had some back luck early in the seasons over the past two or three. Fortunately it’s not as bad as it has been previously.
"That versatility with a bloke like John Bateman who has already shown that he has had to fill in on the edge last week, he moved to the centres a week before through an injury. That is certainly a healthy addition to a squad.
"We’ll have a look at that balance and work out what we’re going to do on the bench and who we move into that area. It’s what you strive for with an NRL squad, to have younger players pushing for NRL spots and depth putting pressure on players who are in their position."
Second-rower Hudson Young is a chance to make his debut while Jack Murchie, JJ Collins, Luke Bateman, and Emre Guler are all pushing for a spot in the top grade.
