I just read this article I was searching for news on Cotto and this is what I found

Top Rank’s Bob Arum will not rule out any of the top names for Miguel Cotto’s planned ring return on June 13. Cotto was originally going to face Antonio Margarito in a rematch, but those plans were scrapped when the California State Athletic Commission revoked Margarito’s license to box on Tuesday, making him unavailable for at least a year. Margarito had his license revoked after the commission ruled that his hand wraps contained a foreign substance. The substance was discovered in Margarito’s hand wraps about thirty-minutes before he entered the ring to fight Shane Mosley on January 24.
Arum doesn’t want to look to far ahead. Cotto still has to deal with Michael Jennings on February 21 at New York’s Madison Square Garden. He plans to sit down with Cotto after the Jennings fight and look over all of the possible names. He won’t exclude anyone, including welterweight champions Andre Berto and Shane Mosley.
“We'll see what makes the most sense. We will be looking at the rankings. We will look at the other champions. A lot of that will depend on where the fight is going to be. If its in The Garden, on the eve of the Puerto Rican Day Parade, then we will go in one direction. If it won’t be there, then we will go in another direction. We know all the names in the welterweight division. We are not excluding anyone,” Arum said.
Mosley is the opponent that makes the most sense on paper, but Arum says that he may not make the most sense to Cotto’s wallet. Cotto won a decision over Mosley in 2007, Margarito knocked Cotto out in July and then Mosley knocked out Margarito last month. Arum would rather go with a fighter like Berto because it means more money to Cotto. A Mosley rematch would mean less money for Cotto because Arum feels, and he’s probably right, that Mosley will demand at least a 50-50 split or more.
“He may not make the most economic sense to Miguel. There might be a fight, that economically, makes more sense. We are going to get Miguel the biggest fight with the most money,” Arum said.
Cotto doesn’t seem to care who the opponent will be.
“That’s never been my job. They present me with choices and tell me which is the best one. If Mosley is the next guy then he’s the next guy,” Cotto said.
