Trainer Roger Mayweather's nephew, Floyd, takes on Oscar De La Hoya in a super welterweight title fight

Trainer Roger Mayweather can work the corner when his nephew, Floyd Mayweather Jr., takes on Oscar De La Hoya in a super welterweight title fight next month.

Roger Mayweather received a lecture Tuesday from members of the state of Nevada's Athletic Commission before they unanimously voted to restore his license, which had been revoked after he climbed into the ring during a fight a year ago.

Mayweather also was fined $200,000 (EUR149,000) for entering the ring in the 10th round of an April 8, 2006, fight between Floyd Mayweather Jr. and Zab Judah. Judah's license also was revoked and he was fined $250,000 (EUR186,300) for punching the back of Mayweather's head and for joining the fracas in the ring.

Commissioner John Bailey said Roger Mayweather had to understand he could have sparked an audience melee at the Thomas & Mack Center, and said he hoped Mayweather regretted the incident.

The veteran trainer and former world champion boxer repeatedly told commissioners that under similar circumstances he wouldn't enter the ring again.

The commission's 4-0 decision clears the way for Mayweather to work Floyd Mayweather Jr.'s corner in the De La Hoya bout at the MGM Grand hotel-casino May 5.

The commission also selected Kenny Bayless as referee and Jerry Roth, Chuck Giampa and Tommy Kaczmarek as judges for the fight.

Mayweather Jr., 30, of Las Vegas, is undefeated in 37 fights and generally thought of as the best kilo-for-kilo boxer in the world. He will move up to 70 kilos (154 pounds) to challenge De La Hoya in a fight that could set purse records for a non-heavyweight bout.

The 34-year-old De La Hoya was training in Puerto Rico on Wednesday, and spoke to reporters during a break. He said he feels as though he's 25 again.

"I have prepared myself better mentally for this fight than all the fights that I've had before," De La Hoya said at the Wilfredo Gomez Gymnasium in Guaynabo, a suburb of San Juan.

De La Hoya said his maturity and experience gives him an advantage over Mayweather.

De La Hoya has a record of 38-4 with 30 knockouts, but is 2-2 in his last four fights.

He chose to train in Puerto Rico, where he has kept a residence for five years, to be near family and friends. He is married to Puerto Rican singer Millie Corretjer.

He has been training with Freddie Roach since March 1. De La Hoya had been trained by Floyd Mayweather Sr. since late 2000, but the elder Mayweather turned down an offer to be in De La Hoya's corner against his estranged son.

De La Hoya has been sparring with ex-rival Shane Mosley and Puerto Rico's Ivan Calderon to increase his endurance and speed.

"The quickness of Mosley has helped me a lot. It's exactly Mayweather's style of fighting," he said. He added that training with Calderon has improved his 'timing,' which he acknowledged was rusty since he's been outside the ring for a year.

"My timing was not the best and to box with Calderon has helped very much," De La Hoya said.
