vacant IBC Super Cruiserweight title by decisioning Nate Miller in Denmark in 2000 over 12 rounds. Thomsen defended the title by 12-round decision over Rob Calloway in 2001. Calloway had won the vacant IBA title in 2000 with a TKO-1 over Troy Weida but, after winning four non-title heavyweight bouts, challenged for Thomsen's title rather than defend the IBA belt. BJ Flores, who would later challenge for world and interim world titles as a cruiserweight and as a heavyweight, won the IBA World super cruiserweight title by unanimously outpointing defending champion Patrick Nwamu over 12 rounds in 2007. Nwamu had won the vacant IBA title in 2006 at New York's famed Madison Square Garden and was make his first defense. Rather than fight in this division, many fighters are often considered to be between cruiserweight and heavyweight in categorization, such as former cruiserweight and heavyweight world champion David Haye, who had to lose weight to fight in the cruiserweight division, while his natural body weight, while over 200 pounds, makes him considered by some experts to be somewhat small in weight for the modern heavyweight he subsequently fought in successfully.
