Cheban beat Valentin Demyanenko of Azerbaijan in a sprint to the finish line. Brazil's Isaquias Queiroz got the bronze — his second medal at the Rio Olympics.
Cheban fell out of his canoe as he pushed himself past the finish line. Queiroz also ended up in the water in the finish area.
Thus, Cheban has become the two-time Olympic champion: he also won the gold medal at the Olympics 2012.
