Sydney Roosters medical staff have assessed the squad following Friday's Round 16 match against the Melbourne Storm at Adelaide Oval.
Dylan Napa sustained an MCL strain in the second half of the match that saw him come from the field.
The Queensland Maroons medical staff will assess Napa throughout the week and determine his fitness for State Of Origin III next Wednesday.
Mitchell Aubusson was a precautionary withdrawal last Friday night after experiencing hamstring tightness at training during the week.
He will head into camp with the NRL squad this week and be available for selection in Round 18.
The rest of the squad made it through the match without injury concern.
