HOCKEY: The United States, coming off consecutive losses to Czechoslovakia and the Soviet Union, must defeat winless Norway to have a hope of making the medal round. In other games, the unbeaten Soviets take on unbeaten West Germany and the Czechs play Austria.

ALPINE SKIING: The women begin the two-day Alpine combined with a downhill run at Nakiska; the slalom portion will be Saturday. Vreni Schneider and Brigitte Oertli of Switzerland are among the strongest in the field. Pam Fletcher and up-and-coming Edith Thys have upset hopes.

LUGE: Miroslav Zajonc of Annapolis and originally Czechoslovakia will compete for the United States in today's doubles despite a cast on his foot and not-the-brightest prospects of a medal. He will be paired with Tim Nardiello and in yesterday's training run they clocked 46.524 seconds, 12th-fastest time. Germans dominate the sport, with Joerg Hoffmann and Jochen Pietzsch of East Germany (who had the fastest training time), and Georg Hackl and Stefan Ilsanker of West Germany among the favorites.

CROSS COUNTRY SKIING: Look for continued European domination in the men's 15K at Canmore Nordic Center. Gunde Svan of Sweden is the man to beat.
