The IBO release their January 2024 world rankings
Established in 1988, the International Boxing Organisation have been running for over 36 years. Based in Florida, the independant governing body have had many notable champions win their belts over the years, such as Thomas Hearns, Lennox Lewis, Ricky Hatton and Roy Jones Jr. to name just a few.
This month, five of the top 15 heavyweights in the IBO's new rankings are British, which is a great advert for boxing in the UK at the moment; and there are three reigning IBO champions from the UK and Ireland.
