Former UFC heavyweight champion Bas Rutten says he's sick and tired of the antics of Nick Diaz , whose failure to comply with the UFC's promotional requirements got him pulled out of a welterweight title fight with Georges St. Pierre In an appearance on The MMA Hour , Rutten called himself a Diaz fan, but he said Diaz needs to shape up and start acting like a professional and stop doing things like blowing off appearances."I was really disturbed by that," Rutten said. "It got to me. I literally had to tell myself, 'OK, let it go.' Because this is a guy with so much talent -- I'm a big Nick Diaz fan also -- and I thought, 'OK, now I'm going to see a fight against Georges, it's going to be great.'"Rutten noted that Diaz has said several times that he's underpaid, and that now his failure to make the St. Pierre fight is going to cost him the biggest payday of his career."He's always complaining about not having money enough, and he does a thing like this? It really was upsetting to me. I had to step away from it because I don't like it," Rutten said. "He wants to keep complaining about money? It's his own fault."Although Diaz has been pulled from the St. Pierre fight, he has been given a fight with former champion B.J. Penn , and if Diaz wins that fight he's expected to get the next crack at the welterweight title. Rutten said that for as frustrated as he gets seeing the way Diaz acts, he'll be excited for the opportunity to see Diaz fight for a welterweight belt."Hopefully, he's going to be smart and show up for the press conference," Rutten said.
