The decisive game between Riemke and Weidenau was canceled when the score was 2: 1 due to crowd riots. Weidenau did not appear in a rescheduled game. After Weidenau protested against a game score, a replay was scheduled to be closed to the public, with Weidenau winning 2-1. Weidenau then rose, while Riemke subsequently rose as well.
