Biarritz hooker Arnaud Heguy has been handed a 20-week suspension for threatening a match official.
Biarritz president Serge Blanco, forwards coach Laurent Rodriguez and Heguy were all handed bans at an LNR disciplinary hearing on Thursday.
Heguy has copped the heaviest sanction - 20 weeks - for a "threatening gesture towards a match official" during the ill-tempered clash with Toulon in Round Five of the Top 14 on September 8.
Rodriguez has been banned for 12 weeks for "threatening words towards a match official." The BO forwards coach was seen cutting the path of referee Sébastien Minery after the match at Parc des Sports d'Aguilera.
Blanco, who was LNR President for ten years between 1998 and 2008, has been banned from the pitch, changing rooms and access corridors in stadiums for four weeks after being found guilty of "misconduct towards a match official." He was seen having words with the match officials at full time.
The club was also fined 3000 Euros.
Former France scrum-half Dimitri Yachvili surprisingly received no further punishment after getting a yellow card for a high tackle on Delon Armitage in the same match.
Biarritz are currently last in the Top 14 standings and face Perpignan on Friday.
