Newcastle superstar Kalyn Ponga spent most of Friday on the toilet battling the effects of a stomach bug, but it was Cronulla who felt sick after he inspired the Knights to a gut-busting 26-22 victory at McDonald Jones Stadium that night.
Including the match-winner in the 77th minute after earning a penalty at the other end of the field, Ponga scored two tries, set up two for Mitch Barnett and Brodie Jones, and kicked three goals from five attempts for a personal haul of 16 points.
Knights coach Adam O Brien said Ponga, who could be seen doubled over and vomiting on multiple occasions during the game, and housemate Connor Watson were both ill in the lead-up.
