Conor McGregor lobbed some fighting words in the direction of the WWE's stable of wrestlers in early August by calling them "messed up p*ssies" during a conference call for UFC 202. He then doubled down on that by posting this tweet a short time later, which eventually led to a number of wrestlers responding over Twitter:

As if that wasn't enough, McGregor then tripled down on his WWE beef by referring to John Cena as a "big, fat, 40-year-old failed Mr. Olympia motherf*cker" during another UFC 202 media session before seemingly accepting a challenge from Ric Flair to fight a group of WWE wrestlers. Wild stuff (and a great promotional tool for UFC 202!).

All of that led to Friday morning's SportsCenter where Seth Rollins was asked to respond to McGregor's trash talk. Rollins said that McGregor sounded like a WWE wrestler and told him to get into the ring with a wrestler if he thinks he's so tough:

"It sounds to me like Conor's taking a page out of our game and trying to sell a couple [of] extra pay-per-views before Saturday. It's just Conor being Conor, he's doing his thing. And if he was serious about it, [the] guy's, you know, 5-foot-6, 145 [pounds] or whatever he walks around at, I don't know. But you can see me here, I'm a full size human being. So if he wants to come around and try to slap the face off me or whatever insult he's got for the day, by all means come step in our ring and see what you got. "

Rollins also took a tongue-in-cheek shot at the UFC champion when Harris asked him if he thinks McGregor would make "a good WWE superstar":

"I think he'd make a fantastic cruiserweight. You know, we got a new cruiserweight division coming where the guys have to be 205 pounds or less. So he could fit right in to there. If he wants to come in the ring with the heavyweights, he might have to eat a few more pizzas and drink some gallons of milk."

This is the type of feud that gives people like WWE owner Vince McMahon and UFC president Dana White giant marketing boners. After all, hype is where the PPV dollars come in (though we should point out that this isn't the first time Rollins has defended the WWE during an attack from someone associated with the UFC). And speaking of PPV dollars, you can watch McGregor fight Nate Diaz at UFC 202 on Saturday night followed by WWE's SummerSlam on Sunday.
