Tony Bellew is known for not shirking a challenge, but he might be facing his toughest yet as he prepares to fight undisputed and undefeated cruiserweight world champion Oleksandr Usyk.
Bellew (30-2-1) is coming off back-to-back wins at heavyweight over David Haye and is stepping back down to 200lbs to try and claim all the gold there.
It will not be easy against Usyk (15-0) who, in less than five years as a professional, is already in possession of the IBF, WBA, WBO and WBC cruiserweight titles.
The Liverpudlian has vowed to retire after this fight, win or lose, but will he be going out with four gold belts or none?
When is Bellew vs Usyk?
The fight takes place on Saturday 10 November at the Manchester Arena.
