Miguel Cotto has reportedly ended his partnership with Jay-Z’s Roc Nation after just two fights together. The two parted ways due to a disagreement over Cotto’s purse for a planned fight with Yoshihiro Kamegai, who had already signed a contract and was waiting for Cotto’s signature when the fight was cancelled. The Cotto-Roc Nation Sports separation was amicable but came about because they simply could not agree on the money Cotto should be paid for the fight, a source with knowledge of the situation said. Cotto, the source said, wanted way more than Roc Nation Sports was willing to guarantee for such a marginal fight that likely would have lost money. Kamegai, who is promoted by Golden Boy Promotions, had already signed a contract for the fight, but it was contingent upon Cotto signing, which he hadn't, and there being a television outlet for the bout, which there wasn't. HBO, Cotto's longtime television home, was not interested in the Kamegai fight unless Cotto had a major fight lined up after it, which he did not, according to a source.
