We're only weeks away from Tyson Fury's epic clash with Oleksandr Usyk but will the winner be boxing's first ever four-belt undisputed champion?
The answer is yes. Many fighters have been undisputed champion in the past when the requirements were decided on what belts were available, with the last being Lennox Lewis after he defeated Evander Holyfield in 1999.
With the WBC, WBA, IBF, and WBO belts all up for grabs on February 17, the winner will go down in history as boxing's first ever four belt heavyweight champion.
Below is a list of previous undisputed champions.
