Watch: Massa’s teammate in karting brawl

Ex-Formula 1 driver Felipe Massa has said sorry after his team-mate Rodrigo Dantas sparked an on-track brawl at the 500 Milhas de Kart event.

Dantas and Tuka Rocha were racing behind leader Massa and repeatedly came into contact with each other before the latter hit Dantas off the track altogether and resulted in both karts heading for the tire barrier.

They both got out of their karts and squared up to each other, then Dantas pinned Rocha to the floor and punched him.

Security guards came rushing in to end the fight and all karts of the two teams – MDG Matrix and Sambaiba Centerbus Racing – were disqualified.
