The NRL will use the final round game between St George Illawarra and Newcastle and the finals of the National Youth Competition to trial a cricket-style decision review system.

St George Illawarra have announced their first major signing for next season, with improved winger Nene Macdonald agreeing to a three-year deal to join the club.

St George Illawarra coach Paul McGregor has confirmed rookie Drew Hutchison will go back to reserve grade and veteran Benji Marshall will be granted a farewell on Saturday.

The Sydney Roosters were far too good for the St George Illawarra Dragons, stampeding to a massive 42-6 victory in what can only be described as a most dominant display.

Fresh from their best performance of the season seven days after their previous benchmark, Roosters coach Trent Robinson was in no mood to discuss the cloud hovering over the soon-to-be dethroned minor premiers.

Paul McGregor is unaware of any moves to shake up the Dragons coaching structure, declaring the issue will be addressed in a post-season review.

star fullback Josh Dugan plans to hit the ground running when he makes his return from surgery on a broken jaw in Saturday's local derby against Cronulla.

Paul McGregor believes under-fire Benji Marshall has plenty to offer the NRL, even if it's not with St George Illawarra.
