At the 2013 World Championships, Dychko beat Satish Kumar and Pfeifer to reach the final once again, where he was to rematch Majidov. Majidov got a convincing win by knocking Dychko out in the final round despite the latter winning the first 2 rounds. Dychko was first knocked down by an overhand. He'd get up but after the referee resumed the fight, Majidov landed the same shot and knocked down Dychko once again. At that point, the referee stopped the fight. Dychko bounced back by winning a gold medal at the 2014 Asian Games. Dychko would reach the final once again at the 2015 World Championships, but he lost to Tony Yoka 0:3.
At the 2016 Olympics, Dychko vanquished Majidov in the first round but would settle for a bronze once again, after losing to Joe Joyce in the semifinals. His amateur record is 181–18.
Professional career
Dychko announced he was turning pro in February 2017. He said he was looking for a rematch against world champion Anthony Joshua.[2] On his debut, Dychko, an abnormally tall boxer, was matched against 6'11 Aubur Wright, an even taller fighter. He was nevertheless able to convincingly beat Wright, stopping him after just 2 minutes in the first round.[3]
