More than a dozen war veterans from Ukraine were on hand when Oleksandr Usyk faced Daniel Dubois at Wembley Stadium on Saturday night and Usyk become the undisputed world heavyweight champion.

Andrii, who lives about 70 kilometers (44 miles) from the front line in eastern Ukraine, had served two years in combat and described his injuries — a concussion and taking shrapnel in his right leg from an exploding land mine — as “minor.” Like so many other Ukrainians, he’s lost friends and loved ones.

The second bout between unified heavyweight champion Oleksandr Usyk (23–0, 14 KOs), who holds the WBC, WBO, WBA, and IBO titles, and IBF champion Daniel Dubois (22–2, 21 KOs) will take place at Wembley Stadium in London on July 19.
