Gamboa had previously signed for a big fight against former lightweight king Brandon Rios (30-0-1, 22 KO). The fight was to take place this past April 14.
For reasons still unknown, Gamboa no-showed at the press conferences for the fight and Top Rank sued him for breach of contract.
Mayweather had this to say about Arum and Gamboa:
Bob Arum has been filling you all up with this [expletive] for years and robbing fighters. He's trying to sue Leonard [Ellerbe] for Gamboa, knowing that he's been treating his fighter wrong...[Bob Arum and Don King] look at it as a promoter because all they care about is the [expletive] money. I care about a fighter's well-being because I'm a [expletive] fighter. I know how it is. I know what it's like to have a broken rib for the rest of your life. I know how it is to piss blood.
Leonard Ellerbe is Mayweather's business partner. When Arum caught wind of what Mayweather said, he denied it in the following statement:
He said what he said, this is great. Again, people read it and they are sort of astonished with the language and everything. And the lawyers read it and they lick their chops. And why he brought it up at all, and said that we were suing Leonard and Mayweather Promotions—maybe he's predicting the future. We're not suing them. Maybe they are expecting to get sued, but we aren't suing them.
Top Rank signed former Mayweather fighter Jessie Vargas (19-0, 9 KO) earlier this week. When Vargas' contract expired, he immediately struck a deal with Top Rank.
The rivalry between Mayweather and Arum is well-documented. The latest trading of fighters could be the next volatile exchange in their long bitter history.
Gamboa's last major public appearance was with Mayweather's entourage that accompanied him to the ring this past May 5 to face Miguel Cotto that included Justin Bieber, Lil Wayne and 50 Cent.
