Melbourne Storm were dealt a double injury blow in their win over the Brisbane Broncos, with Cameron Munster and Suliasi Vunivalu ruled out for several weeks.
Munster fractured his jaw during the second half of Storm's 14-12 win at AAMI Park on Thursday and will miss up to six weeks, the NRL club said.
Vunivalu will miss a game for the first time since his debut last year, a disrupted AC joint meaning he is set for 3-4 weeks out.
A late Josh Addo-Carr try saw Storm past the Broncos in a thrilling win in round three.
The result saw Melbourne continue their perfect start to the campaign, sitting top of the ladder with six points.
They face the Wests Tigers in their next outing on March 26.
