Sydney Roosters forward Dylan Napa will front the judiciary on Tuesday night to plead not guilty to a grade two shoulder charge on Souths opponent John Sutton last week.

Napa risks a four-match ban and any chance of playing in the NRL finals if he is unsuccessful at the judiciary but would have copped a three-match ban with an early guilty plea.

Roosters team-mate Aidan Guerra has taken the early guilty plea for a 'chicken wing' tackle and will miss the qualifying final against Penrith on Saturday.

Canterbury forward Tony Williams is free to face the Storm on Sunday despite being placed on report for a shoulder charge on Aidan Sezer late during the Buldogs' 19-18 loss to the Titans.

James Hasson can line up for the Sea Eagles against South Sydney on Saturday if he takes an early guilty plea for his grade-one dangerous throw on Matt Scott.

Martin Kennedy will be free to play for the Broncos in their elimination final against North Queensland after he was charged with a grade-one careless high tackle on Kevin Proctor.

Kennedy will avoid suspension regardless of his plea, but with Sam Thaiday set to return to the side after serving his ban, Kennedy may not feature anyway.

Gold Coast's Dave Taylor is facing a two-week ban for a head slam on Canterbury's David Klemmer, but he will miss only the first game of next season if he takes an early guilty plea.

Titans Beau Falloon and Tom Kingston face two or three-week bans for a dangerous throw on Josh Reynolds.

Canberra's Brett White can escape suspension after being charged with a grade-one careless high tackle on Darcy Lussick.
