Apparently Ultimo Guerrero’s pin fall loss on 12/9 in Guadalajara to Volador Jr. was a screw up. Guerrero hasn’t lost to anyone since he lost his mask. The ref counted to three after a Spanish fly by Volador Jr., but that wasn’t supposed to be the finish. The two continued wrestling, since it was supposed to be a near fall, but the referee stopped them and raised Volador Jr.’s hand. The ref wasn’t working the show the next week.

Well, arguably, it would have been worse had he not stopped it and let them continue after a three count.

this is what happens when you have legit refs calling matches and not refs taking notes on their ear piece. things like this are bound to happen. I'm not sure if they're building him for something, but it shouldn't hurt him that bad, it's a pinfall loss to a credible wrestler with no stipulations on the line
