Coach Craig Bellamy confirmed the news after his team’s 26-16 win over the Knights.
“They’re (medical staff) thinking its a grade 2, he will probably miss two or three weeks,” he said.
Smith hurt his left shoulder while scoring his 46th career try, which Bellamy joked that he could’ve off-loaded the ball instead.
“I thought he should’ve gone outside to Josh, to make it a bit easier.”
The Storm take on the Bulldogs in round 13 followed by the Roosters in round 14 and then the Eels a week later.
Smith’s injury comes the same week that speculation emerged that the Brisbane Broncos were interested in his signature for 2021.
INJURY UPDATE: Cam has a Grade 2 AC joint injury. He will be out for 2-3 weeks.
