Floyd Mayweather is scheduled to face WBA welterweight champion Marcos Maidana on May 3 in a bout to unify their 147-pound titles.

WBC welterweight champion Mayweather (45-0, 26 KOs) is coming off year in which he had victories over Robert Guerrero and Canelo Alvarez. Maidana (35-3, 31 KOs), of Margarita, Argentina, defeated Adrien Broner on Dec. 14, 2013 by unanimous decision.

"Marcos Maidana's last performance immediately brought him to my attention," Mayweather said in a statement. "He is an extremely skilled fighter who brings knockout danger to the ring. I think this is a great fight for me and he deserves the opportunity to see if he can do what 45 others have tried to do before him — beat me."

Mayweather chose Maidana after running a poll on his website that claimed he'd let fans decide his next opponent. Between the two options of Amir Khan and Maidana, Khan received more votes.
