WWE Hall of Famer Rey Mysterio surprised fans with an appearance at the UFC Mexico event, in the latest example of a crossover between the two companies.

Mysterio was shown on the video screen during the show and was seen to be having a great time. The three-time former WWE World Champion had a beverage and threw up his signature hand gesture as the crowd cheered for him.



Mysterio's presence at the event is just the latest example of a crossover between UFC and WWE. On this week's Raw, Michael Chandler appeared in the crowd with plenty to say. The UFC fighter grabbed the mic and called out Conor McGregor and said he'd "See you at the top."

At UFC 298, several WWE Superstars appeared in the crowd at the event. WWE's resident power couple Bianca Belair and Montez Ford were at UFC 298 as was CM Punk. The Chicago-Made star was described as a "retired welterweight" in a nod to his underwhelming UFC career.

Seth Rollins recently addressed Punk's tenure in UFC. When asked about his prospects in the Octagon, Rollins said he'd do poorly, but would do better than Punk.

In November of last year, Mysterio underwent knee surgery that has kept him out of action ever since. The masked legend had reportedly been putting off the surgery for some time. He was written off of TV with an attack by Santos Escobar as part of the latter's exit from the LWO. While Mysterio hoped to return to the ring in time for the Royal Rumble, that did not happen. It is now believed that Rey will return ahead of WrestleMania 40 in April of this year.
