Nazim 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 hand wraps prior to Margarito’s fight with Mosley, leading to Margarito’s eventual suspension from the sport of boxing.

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.
