Injuries to George Williams and Seb Kris soured a loss for the Raiders, who went down to South Sydney 34-20 at GIO Stadium.

Coach Ricky Stuart was left frustrated at the way the ruck was officiated and then at the bunker which took two tries away from Jack Wighton as the team attempted to fightback.

The Raiders take on the Knights next week in Wagga Wagga, as they look to stop a four game skid.
