“The Best in the World” and The Scottish Psychopath summon The Phenom.

Despite what they might have said on Raw and SmackDown LIVE this week, Shane McMahon and Drew McIntyre – whether they want to admit it or not – showed fear in the presence of The Undertaker when The Deadman emerged this past Monday night.

This apprehension might be why The Scottish Psychopath and “The Best in the World” turned their tag team battle against The Undertaker and Roman Reigns into a No Holds Barred Match at WWE Extreme Rules next Sunday in Philadelphia. With that showdown looming, Reigns will have to team up with a partner of McMahon's choosing against “The Best in the World” and McIntyre on Monday's Raw, as first reported by Sports Illustrated. Plus, if The Undertaker interferes in the match, he's out of this Sunday's matchup.

Who will build momentum for their respective team just six days before Extreme Rules?
