Champion Melbourne fullback Billy Slater could be out for the entire NRL season.

But the Storm are hoping, with some luck, that will not be the case.

Slater will go under the knife this week to determine the damage to his left shoulder, with fears he could require a second reconstruction which would rule him out for the entire NRL season.

The star copped the injury in a knock against St George Illawarra in round one, and happens to be the same shoulder he underwent surgery on last year.

Storm centre Will Chambers says the entire club are hoping he does not suffer the same season-ending fate he did after the second State of Origin match last year.

“It’s disappointing for everyone else around the club as well,” Chambers said.

“Bill is a big part of this club and has been for a long time. It’s very disappointing and everyone has their fingers crossed for some good news over the next couple of days.”

Chambers also said that while Slater was trying to remain positive, he was naturally upset.

“It’s obviously devastating for him,” he said.

“The news that he had to go back in and had to find out what’s wrong with his shoulder is obviously hard.

“He doesn’t know, he’s just got to wait and see what’s in store ahead.”
