A violent fight broke out between two drivers toward the end of a 500-mile Brazilian karting race on Saturday, when a teammate of Felipe Massa tried to pummel a competitor after a crash into the tire barrier.
Rodrigo Dantas, who was driving for Massa’s team, and Tuka Rocha were battling for the lead with 18 laps to go when Rocha sent both karts into the tires. Dantas got out of his car and the two exchanged punches before Dantas threw Rocha to the ground and appeared to attempt to strangle him between numerous punches.
All karts from the two teams were disqualified. A team featuring Rubens Barrichello, his son Dudu and former IndyCar driver Felipe Giaffone won the 12-hour race.
Massa and fellow team leader Thiago Camilo apologized for the incident in an interview with SporTV, with Massa calling it “one of the saddest things of his career,” according to ESPN.
