Melbourne will be without two premiership players for the foreseeable future, after both Tim Glasby and Curtis Scott suffered injuries in the Storm's 50-10 win over the Warriors on ANZAC Day.
Glasby broke his thumb during play in the first half, while Scott suffered a leg injury after it was caught under an opponent during the second 40.
"Unfortunately Tim has suffered a broken thumb and has undergone surgery today – we are expecting him to miss 4-6 weeks of football," Storm Football Director Frank Ponissi told melbournestorm.com.au on Thursday.
"Scans suggest Curtis has suffered a high ankle sprain and he will miss the next few weeks.
"However until his swelling settles we are unable to specify a timeline exactly. We will have a better understanding in the coming days."
The Storm now have an 11-day break before facing off against the ladder-leading Dragons next Sunday.
Winger Suliasi Vunivalu missed the ANZAC Day clash with a hamstring injury, although the Storm expected him to be fit to face the Dragons.
