Giorgio Di Centa is out of the games . A nagging hernia has forced the Olympic champion to return to Italy which means he will miss the 50 k Cross Country Ski on Sunday. Despite the treatments he has received in the last few days, Di Centa has had to surrender to the obvious impossibility of him competing. The Italian will be returning to Italy tomorrow morning and will be visited by the staff of the Fisi Medical Committee at La Madonnina clinic in Milan. The doctors will then decide the best way to solve the problem.
