It should be noted that Tupou is charged with contravening 9.20 which stipulates that:
a) a player must not charge into a ruck or a maul. Charging includes any contact made without binding onto another player in the ruck or maul
It makes no reference as to where contact is made, and in itself has an entry level punishment of 2 weeks.
Obviously if contact above the shoulder line is made, then that's covered by b) A player must not make contact with an opponent above the line of the shoulders, and said punishment increases.
does that still count when the 'opponent' has their shoulders and head illegally lower than their hips? Should have been a free kick to QLD. Sickening bias.
