South Sydney's quest to remain in the top eight has received a hammer blow with star forwards Cameron Murray, David Fifita and Tallis Duncan joining talisman Latrell Mitchell on the sidelines. David Fifita saw his one-game ban increased to two on a poor day for South Sydney. Earlier on Tuesday, the Rabbitohs revealed captain Murray (calf) and in-form edge Duncan (hamstring) would miss up to four and three weeks, respectively. Skipper Cameron Murray joins a bulging South Sydney casualty ward after a calf injury. With Duncan and Adam Elliott both out, the Rabbitohs will need to get creative to cover for Fifita in the second row.
