WWE veteran cuts scathing promo on Austin Theory after SmackDown; calls him "Psycho boyfriend who got dumped"

WWE United States Champion Rey Mysterio had some stern words for the number one challenger, Austin Theory, this week.

Theory tried to interfere during Mysterio's match with Grayson Waller on SmackDown. However, Santos Escobar rushed to ringside and took care of him, even while not at 100%. This allowed the masked luchador to pick up the win with a 619/splash combo on Waller.

WWE correspondent Kayla Braxton caught up with Mysterio and Escobar on SmackDown LowDown. Rey claimed that Theory was behaving like a stalker boyfriend who just couldn't let go of the United States title. He mentioned that the gold now belongs to the LWO, and it would stay there for the foreseeable future.

"Austin Theory is the psycho boyfriend who got dumped by the United States title. You know, this United States title is now with a new owner. It's with me and the LWO. So he can't let go." [From 0:09 - 0:24]
