The halfback dislocated his right shoulder in Origin II in 2021, but returned to steer the Panthers to their first premiership before he had surgery.
Cleary was seen in the sheds after the game in deep discussion with his father and coach, Ivan.
“He hurt it in the pre-season, he had some trouble with it earlier in the year, and then throughout the hamstring issues – he got on top of it, but it’s a recurrence tonight,” Cleary snr said.
“We’re concerned. It was bad enough for him to come off. He explained how he felt and what happened the best he could. I was checking in on him [after the game] more than anything.

“He’s in better shape than he was when he did his hammy. Hopefully that’s good news. What do you do? It’s one of those years I think [for him].”
Cleary had only been back in action a month after suffering a serious hamstring injury that sidelined him for nearly three months.
Jack Cole came into the halves once Cleary departed, and will be the back-up option should Cleary be out in the coming weeks.
James Fisher-Harris was placed on report for a late hit on Storm halfback Jahrome Hughes that led to the penalty that allowed the Storm kick a penalty goal and reclaim the lead they maintained for the final seven minutes.
There was plenty of drama between the two genuine heavyweights, including the sin-binning of Nelson Asofa-Solomona in the 55th minute. Referee Ashley Klein sent Asofa-Solomona for a break for hitting Daine Laurie in the back of the head with “moderate force”.
Asofa-Solomona managed to wipe out teammate Cam Munster in the same tackle. Munster stayed down and bled from the nose, and despite appearing to stumble when he returned to his feet, was cleared to return.
Melbourne kicked two wins clear of the Panthers and locked up a top-two finish with three rounds remaining.
Coach Craig Bellamy confirmed he was now likely to rest players in the final couple of rounds against North Queensland and Broncos, who are both in the finals fight.
