Why did Hasanboy Dusmatov's opponents change?

As you know, recently the champion of the Rio Olympics Hasanboy Dusmatov achieved his second victory in professional boxing. He defeated Odiljon Sotkinov in the first round by technical knockout. Sotkinov originally from Uzbekistan, who rose to the ring on behalf of Russia.

Surprisingly, in this fight, Dusmatov was first known to compete with Russian Artem Tkachenko (5-0, 3 KOs). For some reason, the opponent had to change and face another host Pavel Gurchenko (1-0-0). However, in today's fight, as mentioned above, he went to the ring against Odiljon Sotkinov.

In order to clarify this fact, we appealed to the coach of boxer Ziyatdin Tayganbaev.

“Previously, a representative of the African continent had to be a rival. But they had a visa problem. Later, Tkachenko, then Pavel Gurchenko, had to fight. However, Gurchenko broke his rib the day before the weigh-in. Thus, today's opponent was found, ”Tayganbaev said.
