Referees are being further encouraged to monitor foul play during this season's Super 15 series.
It was confirmed yesterday that they have been told to signal any mid-match concerns to the citing commissioner who can later adjudicate with the benefit of replays.
Referees may not be able to act on some incidents because they have been unsure about a player's identity or they and their assistants cannot be certain whether an offence warranted a red or yellow card.
Even if a referee sinbins a player he can refer the same incident to the citing commissioner for a review.
Citing commissioners are also being encouraged to issue yellow cards if they observe acts of foul play which go unnoticed by the match officials.
