Former South Africa and now Bulls hooker Schalk Brits received the first red card of his career after an old school punch up with Sharks hooker Akker van Der Merwe.
The Sharks number two instigated the brawl when he appeared to headbutt Brits on the floor in a ruck and the former Saracens front rower reacted.
Even after the ball had left the breakdown the pair threw several punches and van Der Merwe looks to have attempted an eye gauge on Brits.
Both players received a red card from the referee and are likely to face significant bans, but were seen enjoying a beer together in the changing room after the game.
Brits made over 200 appearances for Saracens and earned 11 caps for the Springboks and the 37-year-old returned to play in South Africa with the Bulls this season.
