Both contenders will put their unbeaten records on the line in the main event of the card expected to be held at the Odyssey Arena, where Fury defeated Martin Rogan to lift the Irish heavyweight strap in April.
The Brit is 19-0 with 14 knockouts, while 26-year-old Boytsov has not been defeated in his 31 professional bouts, 25 of which came inside the distance.
It will be the first time Boytsov has fought outside of Germany and Austria, and the eliminator will set up 41-year-old Klitschko’s next challenger following his dominant win over Manuel Charr in September.
Fury, 24, has made headlines in recent weeks by calling out fellow British heavyweights David Haye and David Price, with Price next in action seven days after Fury against Matt Skelton while Haye claimed he would never fight again “unless it was against a Klitschko”.
If Fury, who hasn’t fought since stopping American Vinny Maddalone in Clevedon this past July, is able to get past his biggest challenge to date in Boytsov, it will be he and not the semi-retired former world champion Haye who will step up to meet Vitali.
