Gerringong Lions forward Hamish Stewart has been recalled to the St George Illawarra side for Saturday's crucial clash with the Roosters at Kogarah.

Stewart was stood down from last Saturday's 28-24 loss to the Raiders in Canberra after suffering a concussion in the prevoius round when the Dragons knocked off Parramatta at WIN Stadium.

The rookie lock has been cleared to make his return and was named on the interchange bench when Shane Flanagan announced his Round 19 team on Tuesday.

Former Maroons forward Jaydn Su’A will line up for his 150th NRL game after the Samoan international previously played for Brisbane and South Sydney.

He joined the Dragons in 2022 and after winning the Dragons Medal a year ago, he has been one of the team's top performers this season.

Queensland winger Valentine Holmes has been named to back up from Wednesday's State of Origin decider at Accor Stadium, which means centre Corey Allan has been dropped to the reserves.

Veteran second-rower Luciano Leilua has overcome a quad strain which sidelined him last week to also boost the pack alongside Stewart.

Michael Molo has been relegated to the interchange with Loko Pasifiki Tonga and Viliami Fifita now in the reserves.

The Dragons have won just six of theeir 15 starts in 2025 but are still in the playoff hunt in 11th spot, just two competition points behind eighth-placed Manly.

They could leapfrog the Roosters, who are in ninth, if they can topple them at Kogarah this weekend.

The Roosters have five players on representative duty - Connor Watson, Robert Toia, Angus Crichton, Spencer Leniu and Lindsay Collins, while centre Billy Smith (knee), halfback Sam Walker (thumb) and lock Victor Radley (concussion) have also been named to make their return from injury.

This Saturday's match will be a double-header with the NRLW side taking on the Roosters at 3.15pm before the NRL match at 5.30pm.

The club will be celebrating the 15-year anniversary of the 2010 grand final victory over the Roosters with a strong contingent of former players on hand for the clash.
