While Melbourne playmaker Cameron Munster has emerged from COVID-19 isolation ready to take on Canberra on Sunday, hooker Harry Grant is no certainty to start.
The Raiders have also been hit by the withdrawal of winger Nick Cotric, second-rower Elliott Whitehead and interchange forward Corey Horsburgh.
Munster missed Queensland’s State of Origin deciding win after contracting the virus but joined the Storm’s final training run on Saturday ahead of the AAMI Park clash.
