Star Raiders centre Joseph Leilua could miss the rest of the home-and-away season after he was cited for dropping knees in Sunday's loss to Manly.
The 27-year-old can accept a two-match sanction if he submits an early guilty plea, but can challenge the decision without the risk of adding to the suspension.
The ban looms as a major blow for the third-placed Raiders, who are currently locked in a tight battle with the Sea Eagles, Rabbitohs and Eels for the final two top four positions.
The Raiders will travel to PointsBet Stadium to take on the seventh-placed Sharks on Sunday.
