Dragons: Centre Brayden Wiliame needed the assistance of a trainer to limp off the field with a lower leg injury against the Bulldogs on Monday and appears long odds to play. Euan Aitken or Tim Lafai would likely replace him in the starting side.
Sharks: Halfback Chad Townsend (hamstring) and prop Andrew Fifita (calf) are expected to reclaim their starting positions after missing the last-start win over the Cowboys. Townsend's recovery would likely mean Matt Moylan takes over at fullback from Will Kennedy and Shaun Johnson slides back to five-eighth.

Tyson Frizell, who made his NRL debut for the Sharks way back in 2011, will run out for his 150th Dragons appearance while James Graham records a half-century of Dragons appearances.
Tariq Sims and Brayden Wiliame suffered injuries during last week's loss, which brings both Tyrell Fuimaono and Euan Aitken into the starting side.
Adam Clune keeps his spot in the halves alongside Ben Hunt while Matt Dufty joins the bench.
It's been 1837 days (May 31, 2015) since veteran Trent Merrin last faced the Sharks as a Dragon, playing his role in a rivalry that dates back to the Sharks' inception in 1967. Saints thumped the Sharks 42-6.
