Practice injuries knocked Simon Dumont and Torin Yater-Wallace out of the Dew Tour on Saturday, leaving two of America's top Olympic hopefuls in halfpipe skiing on the sideline for the season's first qualifying event.
Dumont hit his head on the halfpipe and endured a concussion. He was conscious but trainers did not clear him to compete.
Yater-Wallace sustained a chest injury and was taken to the hospital to be evaluated.
The 27-year-old Dumont has two gold, two silver and three bronze medals at the Winter X Games and was considered an elder statesman of his sport, which makes its Olympic debut this year.
Yater-Wallace, 18, has two X-Games silvers and a bronze. He spent nearly a week in the hospital earlier this month with a collapsed lung -an injury he couldn't trace to a specific moment during his training.
Yater-Wallace was back on the halfpipe Friday, where he finished first in qualifying. Dumont finished seventh.
