Russian diver Ilya Zakharov, who won gold in the men's three-metre springboard event at London 2012, may have produced one of the worst dives in Olympic history just four years later.
The 25-year-old St Petersburg-born competitor was eliminated at the semi-final stage of the Rio Games’ three-metre competition after a spectacularly poor bellyflop.
Zakharov received a round score of 0.0 from all seven judges, which ended his hopes of defending the 2012 title.
