Oleksandr Usyk focused solely on Tyson Fury

Unified heavyweight champion Oleksandr Usyk will fight only the WBC ruler Tyson Fury, the Ukrainian fighter has said.

"Usyka" was last seen in August when he retained his WBA, IBF and WBO belts after a split-decision victory over Anthony Joshua in Jeddah.

Talks over an undisputed heavyweight contest with WBC-belt holder Fury took place immediately after the fight in Saudi Arabia, but the Brit will instead face Derek Chisora at the Tottenham Hotspur Stadium next month.

"Right now my team is seeking conversations with Tyson Fury, and he is really an unpredictable person, so we can't guarantee when," Usyk said at the Web Summit in Lisbon.

"For me, the idea would be to fight maybe early February or the beginning of March, like March 4, because I am an orthodox Christian.

"During the great fasting before Easter I do not fight, so it should be all before or then after orthodox Easter (April 16).
