After an error-marred first run in the event, Gisler, the 23-year-old leader of the Swiss freestyle ski team, needed to make it count in his second run.
But during his first trick – an attempted backward spin – the 23-year-old crashed into the wall so hard that his skies were knocked off his feet. He then fell into the halfpipe.
Gisler received medical attention but was able to walk away from the away from the halfpipe after several minutes, Swiss daily Tages Anzeiger reported.
Neither Gisler nor his teammates Rafael Kreienbühl and Robin Briguet made it through to the halfpipe finals in an event dominated by the Americans.
