Before her injury, Vaughn was seen as a favorite for a gold medal in the downhill, a stunning fact considering she retired more than six years ago before mounting a comeback to World Cup ski racing.

Her teammate Breezy Johnson is another serious medal contender in that race.

In figure skating, the first medals will be awarded when the team event wraps up with back-to-back-to-back free skate routines, first the pairs, then women, then men.

The U.S.

was in the lead over Japan after Saturday.

There are also medal events in the mixed relay biathlon and men's luge.

The American cross-country skier Gus Schumacher will make his debut at this Olympics in the men's skiathlon, and the U.S.

mixed doubles curling team will take on Sweden and Estonia.

On Saturday, Vaughn completed the second of her two official training runs.

This one was even faster than Friday's.

Neither run was perfect, but her coach Axel Lundsvendal said afterward he felt she showed a clear improvement, especially...

in landing the big jumps on the course at the Tofani Ski Hill.

All of this, of course, is in spite of the ACL tear she suffered in her left knee just over a week ago.

Now she awaits Sunday's race.

Vaughn might have been a favorite before her injury.

This season she had won two World Cup downhill races and reached the podium and three others.
