WWE's Sheamus, UFC's Conor McGregor get in Twitter fight

UFC featherweight Conor McGregor was on SI Now Friday when host Maggie Gray asked him if he could beat WWE's Sheamus in a street fight.

McGregor pulled the "wrestling is fake" card. "I'd whoop his ass," he said. "This is real, what I do."

Afterwards, the two started facing off on Twitter.

Sheamus might have a point. He outweights McGregor by more than 100 pounds.
