(CNN) -- When Piers Morgan pointed out that "Vicious" Victor Ortiz will be "facing a guy that has beaten just about everyone that's come in front of him," the boxing champ told the CNN host, "Fear doesn't even exist in my dictionary anymore. It was one of those things where my upbringing alone got rid of all that." Morgan was referring to Ortiz's upcoming September 17 bout with "Pretty Boy" Floyd Mayweather. Ortiz and his mentor, boxing great Oscar de la Hoya, are guests on Wednesday's "Piers Morgan Tonight." Abandoned by his mother at the age of 8, Ortiz was left to essentially raise his younger brother when his father walked out of the family's Kansas home four years later.
