Frazer Clarke has reacted angrily after he was stripped of a semi-final spot at the World Boxing Championships.
The British super-heavyweight won his bout with home fighter Maksim Babanin in Ekaterinburg, Russia, on a split decision but the Russian team appealed.
The final-round scoring was reviewed and the result was overturned, with Babanin now guaranteed a bronze medal.
“The best moment of my career and the worst happened within a few hours of each other,” tweeted Clarke.
“It’s out of my hands; I just turn up and compete. This has to go to people with more knowledge and understanding of the situation.”
Clarke, 28, from Burton upon Trent, won gold for England at the Commonwealth Games in 2018 and was making his debut in the world event.
