Manny Pacquiao prepares to train (Chris Farina/Top Rank)Manny Pacquiao arrived in Los Angeles from the Philippines on Saturday to finish his training camp for his June 9 bout with Timothy Bradley at trainer Freddie Roach's Wild Card Boxing Club.

Pacquiao arrived just as, a couple hundred miles to the East, Floyd Mayweather Jr. stepped into the ring at the MGM Grand Garden for his bout with Miguel Cotto. Pacquiao, who resumed training on Monday, said he managed to catch a portion of the bout.

"It was a good fight and everyone was happy," Pacquiao said.

Mayweather and Pacquiao are regarded as the top two fighters in the world and boxing fans have been eager for them to get into the ring against each other. But a series of issues, notably the purse split and an agreement on a drug testing regimen, have stalled the match.

When the action resumed, Corrales landed a huge straight right that badly hurt Castillo. Always a great finisher, Corrales jumped on him and landed a series of savage blows that forced referee Tony Weeks to jump in and save Castillo. Neither man was ever nearly close to the same fighter again.

Tragically, two years to the day later, Corrales died in a motorcyle accident in the shadow of Mandalay Bay. The

Essentially, what Mayweather said to Pacquiao, who arrived in Los Angeles from the Philippines on Saturday at about the very moment Mayweather was about to start his match with Cotto, was dump promoter Bob Arum and we have a fight.

It's just been a problem trying to make this fight. The fans and the public are being fooled. Bob Arum does not want to make this fight happen. Once he's free from Bob Arum, will the fight happen? Absolutely.

Manny Pacquiao (Top Rank)Pacquiao is contractually bound to Top Rank, and if he tried to make some sort of end-run, Top Rank would undoubtedly sue and the courts would prevent him from fighting until the matter was determined. That would take way longer than a guy who doesn't have much time left in the sport
