Rey Mysterio recently made his return to WWE, but he was wiped out on this week's episode of RAW, after being attacked by the mystery masked star. Logan Paul attacked Mysterio as he was enroute to the ring to take on Finn Balor, before the masked star stepped up to seemingly write off TV Mysterio for several weeks. Despite how the week started, it seems that Rey Mysterio is celebrating his 51st birthday today, on December 11. Mysterio has been a major name in the wrestling business for more than four decades, and his son, Dominik Mysterio, has since continued his legacy and is currently one of WWE's most popular heels. Despite being family, Mysterio and Dominik have had issues since his WWE debut, and now they remain at odds. Who attacked Rey Mysterio?There are a number of names that have been thrown around when it comes to the mystery attacker who first made his debut at Survivor Series, last weekend. The likes of Austin Theory and Montez Ford are names that have been speculated since it appears that the masked star has a link to The Vision, but it could be more than one man. Paul Heyman has a massive pull on the WWE roster and could have convinced any member of the RAW or SmackDown locker room to help him in recent weeks so that they can join The Vision. It's unclear how long WWE will continue this mystery, but Rey Mysterio will be pushing to find out who attacked him and if it was the same man who took out LA Knight before he was written off TV by Bronson Reed and Bron Breakker. Knight was attacked backstage and then hit with a Tsunami on the top of a car in the same way that Braun Strowman was once assaulted by the Australian star.
