Sydney Roosters prop Dylan Napa is facing a ban of three to four NRL matches for his ugly tackle on Brisbane hooker Andrew McCullough on Saturday.

Napa has been given a grade three dangerous contact charge by the match review committee for his shot that knocked out McCullough in the 24th minute of the Roosters’ loss to the Broncos.

Napa will miss three matches if he takes the early guilty plea, but risks being rubbed out for four matches should he contest the charge and lose.
