Meanwhile, fellow Briton Fournier has a 9-0 professional record and lost an exhibition bout with former world champion David Haye on points in 2021. The 40-year-old got his start in the fitness industry before moving into nightclub business. KSI, 29, is facing his most credible opponent by far this weekend. Here’s all you need to know.
