Representatives for cruiserweight titleholder Krzysztof Glowacki and top contender Oleksandr Usyk made a deal for their mandatory fight and avoided a purse bid scheduled for Thursday in New York, Alexander Krassyuk of K2 Promotions East, Usyk's promoter, told ESPN.com.

Krassyuk said the fight would take place either Sept. 10 or 17 at a site to be determined in Glowacki's native Poland.

"We've been negotiating since April 16th," Krassyuk said. "We wanted to stage the fight in [Usyk's native] Ukraine in a 40,000-seat soccer stadium. We made a substantial offer of $500,000 to the champ but he did not agree. So with my friends [Glowacki co-promoters] Andrzej Wasilewski and Leon Margules we started to look for the acceptable solution. It was found."

The 29-year-old Glowacki (26-0, 16 KOs) won his world title belt in dramatic comeback fashion when he knocked out long-reigning titleholder Marco Huck in the 11th round last August. He made his first defense against former titlist Steve Cunningham in April and won a unanimous decision in another entertaining fight.

"Glowacki won over two world-class fighters in his last two fights and this is enough to conclude that he is the biggest danger for Usyk at the moment," Krassyuk said. "Victory is the result of hard work in the gym and mental work on yourself. We are thirsty for the world boxing glory and ready to take the title home."

Usyk (9-0, 9 KOs), who won the 2012 Olympic heavyweight gold medal for Ukraine, was scheduled for an April 23 tuneup fight before boxing for the title, but withdrew because of a foot injury and instead will go directly to the title fight.

Getting a shot at the belt in only his 10th professional fight fulfills one of the goals Usyk, 29, had when he turned pro in November 2013.

"When we signed Usyk we agreed the plan was for him to become the world champ in less fights than Evander Holyfield. So here we go -- 9-0 Usyk to challenge the first world title in his professional career," Krassyuk said.

Holyfield won a cruiserweight world title by split decision in a memorable slugfest against Hall of Famer Dwight Muhammad Qawi in his 12th fight in 1986.
