Finn Bálor defeated one member of The Undisputed ERA to win the NXT Championship for a second time. Now he’ll have to go through another to retain it.

Bálor will defend the NXT Title against Kyle O’Reilly at NXT TakeOver 31. 

The Prince has reassumed his throne atop the black-and-gold brand after a grueling two-week marathon, first emerging from the first ever Fatal 4-Way 60-minute Iron Man Match in a tie with Adam Cole. Then, Bálor toppled the leader of The Undisputed ERA the next week in an unforgettable classic to once again capture NXT’s most prestigious prize.

O’Reilly went through an arduous test of his own to emerge as the No. 1 Contender. The skilled martial artist survived four other men in the first-ever Gauntlet Eliminator Match to earn his chance at the title.

As a three-time NXT Tag Team Champion, O’Reilly knows plenty about hoisting gold in NXT. But capturing his first singles championship without the rest of The Undisputed ERA — and doing so against one of the most accomplished Superstars in NXT history — will likely prove to be the greatest obstacle he has faced. 

Is Bálor’s reign only just beginning, or is O’Reilly poised to stun The Prince?
