Ex-Chiefs prop Sona Taumalolo and a former New Zealand sevens star Nigel Hunt were red carded after a mass brawl in a match for their French club Grenoble.
The ruckus started just before halftime after Brive prop Damien Jourdain was lifted off his feet by opposite number Taumalolo during a scrum, prompting Jourdain to punch the Tongan.
A mass brawl ensued with replacement players and staff members rushing off the bench to join in. The ferocious melee lasted about one minute as the punches flew and players grappled on the ground, with one Grenoble player tumbling spectacularly over the advertising hoardings as he tried to join in.
Jourdain, Taumalolo and Grenoble center Hunt of New Zealand were all red-carded - meaning that Grenoble started the second half with 13 players against 14.
This then became 13-a-side game as Brive lock Julien Le Devedec was shown a yellow card 20 minutes into the second half, and one further player from each side was sinbinned before the end.
