Take a look at Scott Nicholls and Russian teenager Emil Sayfutdinov brawling at the British Speedway Grand Prix at Cardiff’s Millennium Stadium.
Sayfutdinov was not happy when Nicholls ran him wide for third place in heat five and began pushing at each other as they returned to the pits, where they got off their bikes and started to go at it each other like Ali and Frazier.
Sayfutdinov was fined £375 and Nicholls £312 for this brawl.
