The Sydney Rooster’s winger, who is of Tongan descent, tackled St George’s Illawarra winger Mikaele Ravalawa in the 54th minute of the game at the Sydney Cricket Grounds.
Ravalawa was not injured in the incident, but Tupou’s arm hit him in the side of the head after grazing the top of the ball.
Tupou has been suspended for a week by the NRL and has the option to appeal the penalty to the NRL judiciary. However, if he loses, he will face an additional week on the benches.
