Craig Bellamy has admitted Billy Slater will likely not play against Manly on Saturday.
The 35-year-old is expected to be managed off the back of another gruelling Origin series that saw him awarded his second Wally Lewis medal.
With a crucial run home to the season coming up the coaching staff will look to take a cautious approach with Slater.
"We're pretty sure Billy won't be playing but we will have to check on him," Craig Bellamy said.
"For Billy it was very emotionally draining for him. To play his last game up there and get the result that they got... it was a big occasion for him.
"He will probably sit out this week but hopefully he will be back next week."
None of Storm's six Origin stars will take part in Captain's Run in Melbourne this morning.
They will meet the side in Sydney later today before a call is made on their fitness.
"It might be tomorrow before we even know what we are doing," Bellamy said.
"We will probably be missing two or three to be quite honest, who they are at the moment I'm not too sure.
"It takes a lot out of you physically without a doubt with the pace of the game but probably the hardest thing, especially for younger guys playing early in their Origin careers, the emotional side takes a lot out of them."
"In my experience it takes them three to four weeks to come down from. Everyone is a little bit different but we will check on our guys throughout the day and go from there."
