During a pre-match inspection, no issues are generally detected, but during a match, a boxer's fists can easily sweat inside the gloves. When plaster powder comes into contact with sweat, it hardens, which can increase the hardness of a punch and enhance its lethality.
After the match, Morris's coach exposed Margarito's use of plaster powder in his hand wraps, which caused a huge sensation in the boxing arena. Margarito's coach was permanently banned from boxing by the boxing organization.
The media and colleagues alike condemned Margarito. Boxers who had previously lost to him suspected that he had cheated in past matches.
Margarito, who was once infinitely glorified and feared even by Mayweather and Pacquiao, fell into disgrace. His nickname changed from 'Alien' to 'Plaster Hand.'
Because of this incident, boxing coaches became more meticulous in inspecting their opponents' equipment.
