He is now reportedly undergoing a tough rehab schedule in order to obtain clearance to participate in WrestleMania 33.
Nakamura was used only sparingly at last night's NXT TV tapings, and wrestled just a single match against TJ Perkins. At that point, Balor made a surprise entrance and came in for the save.
After the excitement, Balor got on the microphone to cut a promo, promising fans that although he was not yet "medically cleared" to return, he was coming back soon to claim "what's his".
The NXT champion Bobby Roode and Andrade "Cien" Almas were beating on Shinsuke Nakamura when the return occurred.
Vehicle bomb attack near al-Bab in Syria kills over 40
Last week, the Observatory reported that more than 400 al-Bab civilians had been killed in Turkish bombardments since November. Al-Tawil, a member of the opposition al-Bab military council, said about four fighters manning the checkpoint were killed.
As the lights went off inside the arena, Balor quickly entered the ring to save Nakamura and lay the smack down on both the champ and Almas.
Assuming Balor is indeed medically cleared to compete in two weeks, he would likely be returning on the episode of Monday Night Raw airing March 13th.
It's expected that this segment was for the live crowd only. It's not an ideal spot for the first-ever WWE Universal champion, but a realistic possibly if there's nothing for him to do. At WrestleMania itself, though, Goldberg will be busy with a match against Brock Lesnar, and Kevin Owens is widely expected to have a match against Chris Jericho.
No word on whether WWE officials are planning to use him in a big match at WrestleMania.
