Kristi Terzian, one of the U.S. Ski Team's rising stars, suffered a knee injury in a training accident Wednesday at Saas Fee, Switzerland, officials at the team's headquarters said.

Terzian, 23, of Salt Lake City, injured her right knee during super giant slalom training, said team spokesman Tom Kelly. She was treated at a hospital in Visp, Switzerland, and was to return Thursday to the United States.Team doctor Tom Carlsen reported it is too early to determine the extent of her injury, said Kelly. She was scheduled to be examined by orthopedic specialist Richard Steadman at his Vail, Colo., clinic.

"She's had surgery on this knee several times before," said Carlsen. "The big question is how much she's stretched the repair."

Terzian had arthroscopic surgery on her right knee in 1985 and this past May, and had reconstructive surgery to repair a torn anterior cruciate ligament in 1987.

Last season, her sixth on the national team, Terzian had her best year, scoring points in 17 World Cup races, a record for the U.S. women's squad. She also won the women's giant slalom title at the 1990 National Championships.

"It's disappointing for Kristi," said head women's Coach Paul Major, "but she's been through this before and knows what to expect. She will be back."

It was the second injury to an A Team skier in the past four days.

On Sunday, Edith Thys, 24, Squaw Valley, Calif., fractured her left wrist during an almost identical training run at Saas Fee. Major said he expects Thys to be back on snow by November.
