France's Pierre Vaultier retained his Olympic snowboard cross title despite getting caught in a pile-up during the semi-final in Pyeongchang.
The 30-year-old beat Australia's Jarryd Hughes into silver in the final, with Spain's Regino Hernandez third.
Five-time World Cup champion Vaultier eased through the first round, but was among three riders to fall in the semi and took the last qualification spot.
He produced a confident ride in the final to win his second gold medal.
Further down the field, Americans Nick Baumgartner and Mick Dierdorff collided with Australian Alex Pullin.
Sochi silver medallist Nikolay Olyunin was also involved in the incident and could not finish the race because of injury.
