The 140-pound division will crown an undisputed champion on Saturday night in Las Vegas

Regardless of the exact year in which you consider the four-belt championship era of professional boxing to have begun, undisputed champions of a particular weight division have become a rare phenomenon within the sport.  For clarity sake, the WBO didn't launch until 1988 yet wasn't widely accepted on the same level as the incumbent WBC, WBA and IBF sanctioning bodies until 2004, although even that footnote is somewhat debated among historians.  Either way, the modern era of the past two decades in boxing have produced just four men and three women to hold all four recognized world titles in the same weight class simultaneously.
