Storm forward Jordan McLean will be sidelined for up to six weeks as a result of a Grade Two ankle sprain.
The sydenmosis injury was sustained in the early stages of Storm's Round 17 clash against Brisbane on Friday night.
The 24-year old is expected to return prior to the end of the home and away season in Round 23 when Melbourne travel to Canberra to face the Raiders.
Be at AAMI Park when we take on the Roosters, Saturday 23 July, 7:30pm.
