In the featherweight class, Josef Beránek of Czechoslovakia had won the Inter-Allied Competition. He competed at Antwerp, but lost in the quarter-finals to Eduard Pütsep of Estonia. Pütsep then lost to Heikki Kähkönen of Finland, who lost in the finals to his countryman, Oskari Friman. None of those wrestlers had competed in 1919 or the 1913 world championships. In 1924, Friman moved up a class and won the lightweight gold medal at Paris. Also competing in this class was Enrico Porro (ITA), the 1908 gold medalist in lightweight Greco-Roman who had lost to Beránek at the Pershing Games, but Porro was eliminated after the quarter-finals.
