As noted, Alberto Del Rio was involved in a backstage fight with Lucha wrestler Alan Xtreme (Rafy of Ninja Turtles) over the weekend at Arena Naucalpan in Mexico. The news was first reported by @Luchablog.
Del Rio seemingly confirmed the news on Twitter today, and indicated that the fight started because Xtreme had touched Paige. Del Rio wrote that "you have to prepare to learn a lesson" if you "inappropriately touch my fiancee in front of my face." You can check out his tweet below:
Just to clarify. If you inappropriately touch my fiancee in front of my face you have to prepare to learn a lesson. #Respect— Alberto El Patron (@VivaDelRio) December 12, 2016
