Gun Melbourne halfback Jahrome Hughes is set to miss their last-round clash with Brisbane after limping off AAMI Park with a knee injury late in their win over Gold Coast.
With Hughes in a knee brace post-match and with an initial diagnosis of a medial strain, coach Craig Bellamy said he couldn't see Hughes making the trip north to face the Broncos on Thursday night.
He's hopeful of having his star No.7 available for week one of the finals.
Regularly one of the Storm's best, Hughes set up his team's first try as he escaped from a tackle to grubber kick into the corner for a surging Will Warbrick.
"It looks like he's got a slight medial, they don't think it's too bad but I wouldn't imagine he will play next week as it's a five-day turnaround," Bellamy said.
"He will go for a scan tomorrow ... given how he feels now I don't think they think it's a whole heap of damage but I couldn't imagine him playing next week."
Bellamy said that hooker Harry Grant suffered a shoulder injury although was able to play out the game.
State of Origin rake Grant has come off the bench the past two weeks with Melbourne using his speed out of dummy-half to probe the tiring opposition defence.
"He was sore and it looked like he was going to come off at some stage which is a big call as he's a tough little bastard," Bellamy said of Grant.
"We will check that but again I don't think it's too serious but you'd rather have a few more days for him to recover."
He said that more players could also be left out of the Brisbane game depending on the result of Cronulla's clash with Newcastle on Sunday.
A win would see the Sharks move to two points behind the fourth-placed Storm and still mathematically able to make up their points differential in the final round.
"Depending on what happens we might be looking to play them but we'd like to give them a rest," Bellamy said.
"It will have some sort of influence on the decision but it's no use playing those guys if they're not capable of playing ... that would hurt us in the long run."
