Former UFC middleweight title challenger Chael Sonnen discussed the return of heavyweight legend Fedor Emelianenko and where he stands in terms of his legacy.

Chael Sonnen has some interesting thoughts on the return Russian heavyweight legend, Fedor Emelianenko.

The former UFC fighter criticized Fedor, not for his return to MMA, but for his allegedly shady record during his Pride FC run, as well as his mediocre run in North America.

"Fedor is terrible," Sonnen told Submission Radio. "And Fedor is a very nice guy. I had the pleasure to meet him twice. The first time, I was in line with him at a Starbucks in a hotel in Los Angeles, and he just blended in. He was just a chubby bald guy, with a nerdy sweater, waiting for his latte like everybody else. And I thought, what a nice guy.

"The reality on Fedor is, if you're not fighting in a commissioned fight, you're not fighting in a real fight. It has to be a sanctioned commission fight. This comes right back what we were talking about with Holly and her quadrillion boxing championships. If there's no sanctioning and there's no credibility and architecture, it doesn't count. So everything he did in Japan with a referee wearing an earpiece gets thrown out."

"You've got to come to the States where there's an official weigh-in, where there's a regulatory body, and where there's clearer defined rules, with clearer defined judging. He did that. He did that six times and he went 3-3. That's not exactly an impressive record for a guy that we all keep having to hear is 'the best of all time'. Now God bless him, I love a guy that can come back, but I can tell you first hand, you don't get better not doing something."

Fedor recently revealed that he would announce his signing within the next week. Many expect him to finally compete in the UFC Octagon to complete his incomparable legacy. Sonnen, however, doesn't have much faith in Fedor's chances.

"Fedor got destroyed by guys who are now getting destroyed. Fedor got destroyed by Bigfoot Silva, who by my last count has fought - I believe Frank Mir knocked him out in 18 seconds, I suppose I'd have to re-watch that - but the point is that it's ridiculous. I think it will sell once. I know that I'll tune in, I know that the UFC is going to greatly overpay for him, and good for Fedor, man. I think he did everything right, and he is a nice guy. You know, this isn't my goal to come out and bash a guy, but look, if a guy's terrible a guy's terrible. He's 3-3 in the States, that means he's 3-3."

Several fighters have spoken out about the ridiculous suspension handed out by the Nevada Athletic Commission on Nick Diaz. UFC middleweight and Bloody Elbow writer, Josh Samman penned an excellent piece calling it a 'gross abuse of power', and now the biggest star of the promotion has echoed some of these fighters concerns.

"It's so not right for him to be suspended five years for marijuana," Ronda Rousey told the media while in Australia. "I'm against them testing for weed at all. It's not a performance-enhancing drug. It has nothing to do with athletic competition. It's only tested for political reasons. They say, 'Oh, it's only for your safety to keep you from hurting yourself because you're out there.' Why don't they test for all of the other things that could possibly hurt us?"

"There’s no reason for them to be testing for weed. In athletics, the beautiful thing about it is it separates everything from politics. It shouldn’t be involved at all," she said. "I don’t think marijuana should be part of the conversation at all. I think it’s an invasion of privacy for them to test for it, and they have no right."

Rousey then went on to point out how PED users, like Anderson Silva who fought Diaz on that event, didn't even get punished as much.

"It’s so unfair if one person tests for steroids that could actually really hurt a person and the other person smokes a plant that makes them happy. He gets suspended for five years, whereas the guy that could hurt someone gets a slap on the wrist. It’s not fair. It’s not fair at all."

"I can’t believe this isn't being said more. I think they really should free Nick Diaz, but it’s not (the UFC's) decision either."

The Nevada State Athletic Commission suspended UFC welterweight Nick Diaz for five years on Monday because of the third marijuana-related offense of his career.

The NSAC discussed a lifetime ban for Diaz, 32, before voting unanimously on five years.

NSAC commissioner Skip Avansino acknowledged during deliberations a five-year ban is essentially "a lifetime (ban) for (Diaz)."

Pedro Rizzo returned to action Saturday after a hiatus of more than two years. After a win in his native Brazil, the heavyweight announced his retirement.

The 41-year-old Rizzo (20-11) fought Andrew Smith at Face to Face 12’s main event in Vitoria, Brazil. Rizzo’s leg kicks were too much for Smith after five minutes, and he didn’t answer the bell for Round 2, giving “The Rock” a TKO win in his finale.
