Alberto Del Rio — ATTACKED By Fan While Wrestling in Puerto Rico (VIDEO)

WWE United States Champion Alberto Del Rio was attacked by an overzealous fan sitting ringside for his match Saturday in Puerto Rico — and the whole thing was captured on video.

Del Rio was wrestling Ray Gonzalez for WWC to fulfill contractual obligations he made prior to re-signing with WWE, but one fan got violent when he dodged out of the ring for a breather.

As you can see in the video, the masked fan hits ADR with a few clubs to the back before a hoard of security run in to break things up. Gonzalez pulls Del Rio away from the chaos and the two bring the match back into the ring.

If you’ve ever wondered why WWE generally doesn’t allow talent to work for outside promotions, watch the video — you’ll find your answer.
