Storm forward Jesse Bromwich will miss 4-6 weeks as a result of a grade two hamstring tear suffered in Sunday's win over Brisbane.
The New Zealand international suffered the injury in the second half of the Round 14 clash after lunging to make a tackle.
It is a big blow for Bromwich and Melbourne who will be without the leader of their forward pack for the next month. Bromwich returned to the Storm side from a knee injury in Round 12 after missing four weeks earlier in the season.
Match: Knights v Storm
