Naazim Richardson is an American boxing trainer most notable for training "Sugar" Shane Mosley and Bernard Hopkins, and for catching Antonio Margarito with a plaster-like substance in his handwraps prior to Margarito's fight with Mosley, leading to Margarito's eventual suspension from the sport of boxing.
Richardson was raised in Philadelphia, Pennsylvania and left home when he was 14. He was jailed as a teenager. According to the New York Times, "Boxing took Richardson from the streets that almost swallowed him in north Philadelphia, gave him energy and purpose." 
Richardson is a devout Muslim.
In 2007, Richardson suffered a stroke that nearly caused loss of the entire left side of Richardson's body.
Soon after returning to boxing, Richardson became "Sugar" Shane Mosley's trainer for three of the biggest fights of the boxer's career - his win over Margarito and his loss to both Floyd Mayweather, Jr. and Manny Pacquiao.
Richardson is currently Bernard Hopkins head trainer.
