Their rivalry will finally be settled, when Olympians Michael Conlan and Vladimir Nikitin collide on the undercard of Terence Crawford-Egidijus Kavaliauskas.

The event is scheduled to take place on Saturday, December 14 at Madison Square Garden in New York City.

The contest will be a rematch of their highly controversial 2016 Olympic quarterfinal bout - which saw Nikitin walk away with the win and Conlan flip off the judges.

Conlan (12-0, 7 KOs), who is ranked in the top 10 as a featherweight by three of the major sanctioning organizations, is looking to avenge the final, and most controversial loss, of his amateur career.

Conlan is coming off a rousing TKO win over Diego Alberto Ruiz on August 3 in front of 10,000 hometown fans at Belfast’s Falls Park. He was initially scheduled to face Nikitin on that date, but an injury forced the Russian boxer to withdraw.

Nikitin (3-0, 0 KOs) did not turn pro immediately following the 2016 Olympics, electing to fight as an amateur throughout 2017. He signed a professional contract in 2018 with Top Rank, in large part because he wanted to face Conlan as a pro.

"I'm beyond excited to fight for the sixth time in my favorite venue in the world, the Mecca of Boxing, Madison Square Garden,” Conlan said.

“The boxing fans in New York City have been incredibly supportive of my career, and I look forward to putting on another great show for them, as well as my Irish fans coming over for this massive holiday event. Vladimir Nikitin and I have unfinished business from the 2016 Olympics, and I can't wait until December 14 to set the record straight."

Nikitin also wants to set the record straight, and believes Conlan will suffer yet another defeat.

“Michael Conlan has done a lot of talking about me and our Olympic fight over the last few years. The talking finally ends December 14,” Nikitin said.

“He’s bitter over our last fight and can’t accept the result. Well, my hand will be raised once again.”
