The Security Service of Ukraine (SBU) extended its best wishes to boxer Oleksandr Usyk as he prepares for his match against British fighter Daniel Dubois.

A post on SBU's official Facebook page included a joint photo of Usyk and SBU head Vasyl Maliuk.

"Today, the whole of Ukraine stands with you, Champion! Oleksandr, in the ring you are not just a fighter; you are a symbol for all of Ukraine, which never gives up. Millions of hearts will fight alongside you: those in the trenches, conducting operations, saving the injured in hospitals, and supporting the front from behind the lines.

Show the world once again what Ukrainian character, discipline, skill, and precision mean! We believe in you. Victory will be yours!", the post stated.

Remember, the Usyk – Dubois fight is set to take place today, July 19, at Wembley in London. The champion will host an online marathon covering all the exciting events of the week leading up to this vital match of the year.
