context_page_description: In combat sports where champions are decided by a challenge, the lineal championship of a weight class is a world championship title held initially by an undisputed champion and subsequently by a fighter who defeats the reigning champion in a match at that weight class. In professional boxing, the lineal champion is informally called "the man who beat the man".
  Champions recognized by sanctioning bodies such as the World Boxing Association, World Boxing Council, or the Ultimate Fighting Championship may vacate their title voluntarily, or be stripped of the title for breaching the sanctioning body's regulations or contracts. There will thus be a breach of continuity in the list of sanctioned champions which the lineal championship is intended to prevent. However, there is no single canonical list of lineal champions at any weight class, because there is no agreed upon method of determining the starting point for each lineage and conflicting opinions on what to do when the current champion retires or moves to a different weight class, although there is agreement that any stripping of a title be discounted.
