Off the mark: Judo brings Russia first gold at Rio Olympics
The 30-year-old Mudranov, who hails from Kabardino-Balkaria in the south of Russia, overcame his opponent, Yeldos Smetov of Kazakhstan in extremely tense and close bout at the Carioca Arena 2.
Neither athlete was able to find a winning move during regulation time, which meant the bout went into overtime.
After 44 seconds of the extra period, Mudranov produced a Sasae Tsurikomi Ashi throw, to finally claim victory.
The bronze medals went to Japan’s Naohisa Takato and Diyorbek Urozboev of Uzbekistan.
