Seth Rollins calls out McGregor: See what you got in the WWE ring

Conor McGregor has been very vocal about his disdain for the current roster of WWE stars, repeatedly referring to them as "dweebs" and describing John Cena as "a big, fat 40-year-old failed Mr. Olympian."

WWE's Seth Rollins was given an opportunity to respond to McGregor's comments Friday on ESPN's "SportsCenter," and issued a challenge to the UFC featherweight champion.

"If he was serious about it, guy's 5-foot-6, 145 or whatever he walks around at, I don't know," Rollins said, according to CageSideSeats.com. "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 into our ring and see what you got."

Rollins thinks McGregor could do well as a pro wrestler, with one condition.

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