Gerard Sutton has been appointed to what is arguably the match of the round in Perth when the Dolphins take on the Sydney Roosters, with both teams in the mix for the top eight and top four respectively.
He will be backed up by Liam Kennedy in the bunker after he handled Origin 1 from the same position.
Kennedy will be the on-field official for the Sharks and Rabbitohs on Saturday evening, while Peter Gough handles the Queensland derby between the Gold Coast Titans and Brisbane Broncos.
Here are all the appointments across both the NRL and NRLW this weekend.
