Melbourne fullback Billy Slater will miss Sunday's clash against the nib Newcastle Knights due to a hamstring complaint.
While he was named in the team, medical staff made the decision to rule him out for the game at McDonald Jones Stadium late this week.
"We made a big decision this afternoon in consultation with the medical staff and Billy that we are not going to play him this Sunday," Storm football manager Frank Ponissi told the Storm website.
"He's been training really well trying to build that strength in his leg.

"He could have played but there's still a slight risk he could re-injure it and if he does re-injure it that is going to put him out for a number of other weeks."
While unable to play this weekend, the Storm believe he will be given the all-clear for Origin II.
"It was awfully close (to playing this Sunday)," Ponissi said.
"He will be right to play in Origin 2, it was still a slight risk with the hamstring so we've decided to rest him this particular weekend."
