South African referee Pro Legoete's days on SANZAR's refereeing panel for the remainder of the tournament could be coming to an end soon.
Legoete was at the centre of a dubious decision which saw Waratahs lock Pat O'Connor wrongfully red carded in last week's loss against the Bulls in Pretoria.
Legoete, who was an assistant referee in that match, called referee Craig Joubert and reported that O'Connor "head-butted" Bulls lock Flip van der Merwe.
Acting on Legoete's information, Joubert gave O'Connor his marching orders, but the Waratahs lock was later cleared of any wrong doing.
The incident occurred 15 minutes before the match ended with the Bulls leading 20-17 and although the Waratahs finished the match strongly - despite having only 14 men on the field - the Bulls landed another penalty to secure a 23-17 win.
SANZAR referees boss Lyndon Bray said the red card decision was reviewed and it was clearly wrong.
"There are two aspects which are frustrating. The description of the event was not very accurate. The process between the referee and the assistant referee was not good. It never fleshed out the details of the incident," he told The Australian.
"I've spoken to Craig Joubert about how he could have handled it better, to get better information on which to base his decision.
"Craig was very disappointed he ended up with that decision."
Bray believes Legoete did not communicate the nature of the offence accurately as he hesitated when pointing out the headbutt and he initially indicated that he did not think it was a red-card offence.
"Referees are prone to make mistakes all the time," said Bray.
"What we don't want is a mistake to be compounded by a process that is not good.
"An experienced referee's job is to pick up on messages he is getting. When Pro said no to a red card, clearly there was a message in that.
"It's difficult in the heat of the moment. Craig believed he was dealing with a headbutt.
"If they had talked through what happened, maybe they would have come up with a different outcome."
Legoete won't be in action in a Super Rugby match this weekend and Bray will decide soon whether to stand him down for the last round of the competition.
If Legoete is stood down it won't be the first time as he suffered a similar fate in March last year indefinitely.
