Welterweight, Greco-Roman (≤78 kg), Men

Date	16 – 19 October 1964
Status	Olympic
Location	Komazawa Gymnasium, Komazawa Olympic Park, Tokyo
Participants	19 from 19 countries
Format	Scoring by negative points, with negative points given for any result short of a fall (win by fall-0; win by decision-1; draw-2; loss by decision-3; loss by fall-4). Accumulation of 6 negative points eliminated the wrestler. When three or fewer wrestlers remained, they advanced to a final round, with preliminary results carried forward.

After four rounds four wrestlers were tied with 5 bad points – Kiril Petkov of Bulgaria, Anatoly Kolesov of the Soviet Union, Bertil Nyström of Sweden, and Bolesław Dubicki of Poland. In round five Kolesov and Nyström drew, as did Petkov and Dubicki, which left them all with 7 bad points and theoretically eliminated, so that required another round to determine the medalists. In that round Petkov and Nystrom drew, as did Nystrom and Dubicki, which meant that Kolesov’s victory by decision over Dubicki was the determining factor to give Kolesov the gold medal. Petkov won the silver medal over Nystrom based on lower bodyweight. Kolesov was World Champion in 1962-63 and would win again in 1965.
