Antonio Margarito Montiel is a Mexican-American former professional boxer who competed between 1994 and 2017. He held multiple welterweight world championships, including the WBO title from 2002 to 2007, the IBF title in 2008, and the WBA (Super) title from 2008 to 2009. He also challenged three times for a light middleweight world title between 2004 and 2011. Nicknamed El Tornado de Tijuana, Margarito was known for his aggressive pressure fighting style and exceptionally durable chin.

<span class="mw-page-title-main">Zab Judah</span> American boxer

Zabdiel Judah is an American former professional boxer who competed from 1996 to 2019. He held multiple world championships in two weight classes, including the IBF and WBO junior welterweight titles between 2000 and 2004; the undisputed welterweight title in 2005, which included a reign as the lineal champion from 2005 to 2006; and the IBF junior welterweight title again in 2011. Judah's career ended in 2019 when he was hospitalized after suffering a brain bleed in a stoppage loss to Cletus Seldin.

Jermain Taylor is an American former professional boxer who competed from 2001 to 2014. He remains the most recent undisputed middleweight champion, having won the WBA (Undisputed), WBC, IBF, WBO, and The Ring middleweight titles in 2005 by beating Bernard Hopkins, and in doing so ending Hopkins' ten-year reign as middleweight champion. This made Taylor the first, and to date, only male boxer in history to claim each title from all four major boxing sanctioning organizations in a single fight. He once again defeated Hopkins six months later, making him the only fighter to have defeated Hopkins twice. He retired as a world champion in the months that followed his capture of the IBF middleweight title for a second time, after making a substantial recovery from a brain injury sustained earlier in his career.

In boxing, the undisputed champion of a weight class is the boxer who simultaneously holds world titles from all major organizations recognized by each other and the International Boxing Hall of Fame. There are currently four major sanctioning bodies: WBA, WBC, WBO, and IBF. There were many undisputed champions before the number of major sanctioning bodies recognizing each other increased to four in 2007, but there have been only 19 boxers to hold all four titles simultaneously.

He went on to make a full recovery after spending 19 months out of the sport, meanwhile recovering from severe operation-induced injuries generally perceived as crippling.

<span class="mw-page-title-main">Lineal championship</span> Boxing championship

In combat sports where champions are decided by a challenge, the lineal championship in a weight class represents an intangible world title initially held by the victor of a bout between top contenders in the division. An alternative perspective suggests that vacancies in divisional championships can only be filled by an undisputed champion. A fighter who defeats the reigning champion in a match within that weight class becomes the next lineal champion. In professional boxing, the informal term for the lineal champion is "the man who beat the man."
