The referee did act
Sharks lock Pieter-Steph du Toit has been issued with an off-field yellow card.
He was accused of having contravened Law 10.4 (e): Dangerous Tackling - during the Sharks' 22-25 loss to the Highlanders in a Super Rugby match in Dunedin at the weekend.
Du Toit was rule to have made contact above the line of the shoulders of Highlanders player Jarrad Hoeata at a maul.
The incident occurred in the 51st minute of the match at Forsyth Barr Stadium in Dunedin on Saturday.
An off-field yellow card may be issued by the SANZAR citing commissioner for foul play incidents that are very close to, but in his opinion do not meet the red card threshold for citings.
In this case the referee for the match did act upon the incident by penalising the player for his actions.
Upon further review of the match footage the citing commissioner deemed an off-field yellow card as appropriate.
