Context paragraphs:
Professional wrestling weight classes: In professional wrestling, a weight class is a standardized weight range for the wrestlers.  The top class in almost every promotion is heavyweight, but super heavyweights exist.  Weight class matches in modern-day American professional wrestling are rare, but weight class championships still exist.  However, Japanese professional wrestling, Mexican wrestling and British wrestling use the weight classes more seriously.

List of current mixed martial arts champions: Mixed martial arts (MMA) is a form of competitive combat sport, akin to boxing, muay thai, or kick boxing.  MMA titles, or championship belts, are given to those fighters deemed by a promotional organization to have met a certain standard of athletic accomplishment in a specific weight class (most often by means of a championship fight).  Championship belts are fought for at each weight class under a promotion, with only one belt awarded per class.  Each belt is usually contested every time the belt holder fights, and passed to the victor of that fight (see the List of UFC champions for a chronology of UFC title belts).  A belt may be vacated when a fighter leaves a promotion, or is suspended.  At such times an interim champion may be crowned, or the belt may be awarded to the winner of a fight between top contenders.

Manuel Roman: Manuel Roman is a Mexican professional boxer from Paramount.  As of early 2015 he had 17 wins, 3 losses, and 3 draws.  Roman currently fights in the super bantamweight division.

He was scheduled to face Diego De La Hoya on February 27, 2015.

Taekwondo weight classes: In taekwondo, a weight class is a standardized weight range for taekwondo practitioners.

A taekwondo gyeorugi is usually scheduled for a fixed weight class, and each practitioner's weight must not exceed the upper limit.

Ricardo López (boxer): Ricardo “El Finito” López Nava (born July 25, 1966) is a retired undefeated Mexican professional boxer.  As a professional, he defended the Lineal and WBC Strawweight Championship a record 21 times.  He also won the WBA and WBO Championships in the same weight class.

Weight class (boxing): A weight class is a measurement weight range for boxers.  The lower limit of a weight class is equal to the upper weight limit of the class below it.  The top class, with no upper limit, is called heavyweight in professional boxing and super heavyweight in amateur boxing.  A boxing match is usually scheduled for a fixed weight class, and each boxer's weight must not exceed the upper limit.  Although professional boxers may fight above their weight class, an amateur boxer's weight must not fall below the lower limit.  A nonstandard weight limit is called a catch weight.

Diego De La Hoya: Diego de la Hoya (born August 13, 1994 in Mexicali, Baja California, Mexico) is a Mexican professional boxer in the Super Bantamweight division.  De la Hoya has represented Mexico in international tournaments and is one of the top rated Super Bantamweights in the country.

Rey Vargas: Rey Geovani Vargas Roldán (born November 25, 1990) is a Mexican professional boxer.  He is the current WBC super bantamweight champion.  He is known for his large stature for the weight class and his ability to box sharply on the outside.  Vargas is trained by coaching legend Nacho Beristain.

Gilberto Ramírez: Gilberto Ramírez Sánchez (born June 19, 1991) is a Mexican professional boxer.  He has held the WBO super middleweight title since 2016, and is the first boxer from Mexico to win a major world title in that weight class.  As of September 2017, Ramírez is ranked as the world's best active super middleweight by BoxRec, and second by "The Ring" magazine and the Transnational Boxing Rankings Board.

Lineal championship: 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 (WBA) or World Boxing Council (WBC), or the Ultimate Fighting Championship (UFC) 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.
