Nick Diaz boxing coach Richard Perez is accusing his pupil of stiffing him on his cut of his payout from the Georges St. Pierre fight, and refusing to give him a contract for the Anderson Silva fight.

Perez has been a staple of the Diaz camp for much of Nick, and Nate’s careers, however he claims that he was never paid after the GSP fight, and as a result stopped training Nick Diaz the month of UFC 183. Perez revealed that Nate Diaz on the other hand pays him very well, which may be in part to a different manager.

He explains to Submission Radio:

“Well what happened was you know when he fought his last fight – not this one with Anderson Silva, but when he fought George St. Pierre — I didn’t get my percentage on the pay, and I don’t know what happened with the mix up with the manager and Nick. And then so he let the other manager go and he hired this other man named Lloyd [Pierson] as the new manager and they met [up at] my gym; and you know we renegotiated for the purse, and I asked for a contract and they said it was fine. That was in October. So then I started training Nick and I kept calling Lloyd and I wasn’t getting no contract. So I just felt like, you know I think it was around the 12th of January I decided I don’t want to do this anymore, because I don’t want to get burned. So I texted Lloyd and told him I’m not going to do this unless I get my contract like you promised me, and that’s what happened. They didn’t want to give me the contract so I felt like I didn’t want to get burned again. But I guess I did. It’s sad because I brought him all the way up to the top, and this is what they talk about his, striking and he gets…this guy’s a legend and he gets a big pay, and then I’m being pushed aside. So you know, that’s what happened. So yeah I’m hurt about it. You know and it’s sad because you have a relationship with a guy, [you] teach him to do something that he doesn’t know, and you bring him to the top and he breaks the record for throwing the most punches; and all of a sudden I’m out.”
