Sydney Roosters prop Dylan Napa has been hit with a two-match ban by the NRL judiciary on Tuesday night.

Napa pleaded not guilty to the grade two shoulder charge levelled against him following a hit on South Sydney captain John Sutton early in the Roosters' final round win on Thursday, in a bid to play in Saturday's qualifying final against Penrith.

He was found guilty of the charge by the panel of Mal Cochrane, Don McKinnon and Michael Vella and his defence counsel James McLeod subsequently sought a downgrade of the charge.

After further deliberation the panel judged the hit to be a grade one offence.
