Sione Katoa's finals campaign is in serious jeopardy with the NYC star facing suspension for a shoulder charge against Manly.

Even with an early guilty plea, prior offences mean Katoa is facing two weeks on the sideline, which will rule him out of the Grand Final if the Panthers progress that far.

In better news, fullback Brent Naden escaped without charge after being put on report for a tackle just before halftime.
