Fight fans may be calling for Ronda Rousey to face Invicta featherweight champ Cris Cyborg, but UFC commentator Joe Rogan has some reservations.

While the UFC women's bantamweight champion has competed at 145 pounds in the past, Rogan believes Cyborg's unfortunate PED history needs to be taken heavily into consideration.

According to Rogan, there are problems booking Rousey against Cyborg at any weight.

"Let's look at this rationally," Rogan said on his podcast. "Let's say we know for sure, because we don't know anything for sure, but let's say for sure Ronda is not juicing. Let's say we also know for sure that Cyborg might be on something. That she might be on something to make 145 [pounds]. Then, are you OK with it? Are you OK with it if they both fight at 145 and one person is naturally bigger and might be on something?"

Rogan admits there may be a double standard to how we perceive the risk of Rousey competing in a questionable booking, one we wouldn't assume for men.

"This is my question: Do you have a different opinion about this with women than you do with men?" said Rogan. "Here's a perfect example. Chris Weidman, a dominant champ just like Ronda, if he was going to fight Vitor Belfort and we knew that Vitor might be on TRT, I still wouldn't have a problem with it. I don't think Weidman would have a problem with it, either. I think Weidman would be like, 'I'm still going to f**k this guy up.' That's the point, it's a different fight. Vitor off the s**t or on the s**t.

"That's the question. If [Cyborg's] capable of doing something that's not natural to stay at 145 or get up higher than 145 into the 170's, then how do you feel about the fight? Then it becomes a different fight. What if Ronda loses and then Cyborg tests positive?"

Rogan buys into the notion Rousey is held to different standards, not that's he's comfortable with it, himself.

"This is the sexist in me," said Rogan. "I have more of an issue with it, for some reason, with women. I'm not comfortable with it. What I'm saying is I'm not even comfortable with my opinions on it. Why do I have a different opinion if it's women and the woman was on something? I don't know why."

As for where the fight happens at all, Rogan doesn't understand the pressure for Rousey to punch above her weight.

"This idea that Ronda has to move up? She doesn't," said Rogan. "Why does she have to do anything? She's the champ. This is not a matter of [Cyborg] not being able to [make 135 pounds], it's a matter of her not taking any of the steps to attempt to do it. If you really want to do it you hire Mike Dolce and you put up a video of you making that weight. 'Hey I'm weighing in. 135. See, I can do it. Ronda, let's do this bitch. I want my title.'

"Bam. Biggest fight ever."

FANPOST OF THE DAY

Today's Fanpost of the Day comes via Emmery Myers.

Why is WSOF getting a pass on Rousimar Palhares?

Seemingly lost in all the finger wagging at Steve Mazzagatti and Rousimar Palhares is World Series of Fighting's role in facilitating this circus. It has been rather easy for Ray Sefo and Ali Abdel Aziz to revel in the MMA media storm surrounding the fallout of WSOF 22. After all, they are getting an awful lot of coverage for an event placed opposite one of the biggest UFC events of the year. You have Aziz tweeting about "Sefo dropping the hammer" and Sefo coming on the MMA Hour for a personal mic drop moment instead of going to the fighter's agent or lawyer first, apparently in violation of Palhares' contract. ...
