The International Auto Sports Federation, auto racing's top authority, Wednesday canceled the 1993 World Sports Car Championship because of declining interest by manufacturers. The Sports Car Championship, which featured sleek and prototype Ferraris, Porsches, Jaguars and Peugeots battling in such races as the Le Mans 24 Hours, was a near-washout this season. The championship originally was canceled in January, then revived after some manufacturers said they were committed to this year. Lack of interest and money, however, is resulting in fewer than 10 cars being present for the final races of the year. Fred Clarke, the first driver to die at New Hampshire International Speedway, was killed by the severe impact of the crash, not by spinning violently, according to Dr. Merwyn Bagan.
BOXING: Julio Cesar Chavez, the WBC super lightweight champion, will fight Greg Haugen on Dec. 5 in Caesars Palace at Las Vegas. Former WBA heavyweight champion Michael Dokes won a 10-round split decision over Jose Ribalta in Miami.
