Karim Rasheed Mayfield (born December 14, 1980) is an American professional boxer who fights at welterweight.
Mayfield was a football player, running back, in school and discovered boxing at a relatively late age when he was 20 years old.
[2] Mayfield first won the Vacant NABO Jr. Welterweight on October 1, 2011 in Tunica, Mississippi, via a 10 round unanimous decision against lefthanded former two-time Venezuelan Olympian Patrick Lopez (20-4).
On June 20, 2015 Floyd Mayweather Jr told ESPN Boxing reporter Dan Rafael[3] that he was going to fight either Karim Mayfield or Andre Berto next.
Most boxing scribes did not take this seriously, but Mayweather insisted[4] that he was not joking, stating "Pacquiao fought (Chris) Algieri, so why not?"
