text: CYCLING - BUGNO CLEARED OF DOPING . MILAN 1996-08-27 Veteran Italian Gianni Bugno has been cleared of doping after testing positive for high levels of testosterone during the Tour of Switzerland in June , the Italian cycling federation said on Tuesday . " He has been cleared . The case is closed , " a spokesman said . Bugno tested positive for the banned hormone after the fifth stage of the Tour , in which he finished third overall . But the spokesman said subsequent tests in Cologne proved his body produced higher-than-average testosterone levels naturally . Bugno , who won the Giro d'Italia in 1990 and two successive world titles , was banned for three months in 1994 after testing positive for the stimulant caffeine .
