Although the real reason is still unclear at this point, the storyline reason is that Escobar wants to face Kross on his time and terms. However, as per NXT GM William Regal, the leader of Legado del Fantasma will have to face the former NXT Champion on next week's episode. If he fails to show up, he will be stripped of the Cruiserweight title.
With such an extreme condition, it seems that Escobar will have no other choice but to face Kross next week. That's unless he tries to find some other way to avoid facing The Herald of Doomsday.
Since Kross vs. Escobar was the planned main event for tonight's NXT, Regal name a replacement in a six-man tag team match. Pete Dunne and NXT Tag Team Champions Oney Lorcan and Danny Burch will face Roderick Strong, Kyle O'Reilly, and NXT Champion Finn Balor.
The Undisputed Era still have to figure out why Adam Cole attacked O'Reilly and Balor at NXT TakeOver: Vengeance Day.
Karrion Kross' feud with Legado del Fantasma on NXT
Karrion Kross has been feuding with Legado del Fantasma for the past few weeks. The heat between the two Superstars stemmed from a scathing remark that Escobar made towards Kross and Scarlett a few weeks ago.
Even on last week's show, the NXT Universe witnessed Kross systemically take out Legado del Fantasma's Joaquin Phoenix and Raul Mendoza.
Now that Escobar has drawn the ire of Karrion Kross, he has no choice but to meet him inside the NXT ring at the Capitol Wrestling Center next week.
