Storm NRL squad members Cameron Munster and Harry Grant will each miss at least two rounds of the competition due to injury.
Munster (foot sprain) and Grant (hamstring) have been ruled out of Magic Round this weekend and the round 11 trip to Canberra after having their injuries confirmed by scans.
Munster suffered his injury in the win against South Sydney last Thursday and it prevented him from training with the squad yesterday.
Grant suffered his hamstring tear during that session.
Storm General Manager - Football Frank Ponissi said the club was hopeful of having both players available for the round 12 Indigenous Round match against Brisbane.
"That would be best case scenario for both Cameron and Harry," he said.
"If that doesn’t happen we expect they would both be okay for the opening State of Origin match in Melbourne."
