TUPELO, Miss. — Former WWE and World Champion Rey Mysterio shocked the WWE Universe when he returned unannounced at a WWE Live Event in Tupelo, Miss., yesterday. The Master of the 619, out of action since Feb. 4 as the result of lingering injuries to his left knee, helped R-Truth fend off a post-match attack by World Heavyweight Champion Alberto Del Rio.

News of The Ultimate Underdog’s surprise return first broke on WWE’s social media accounts, with a Tout capturing footage of his ring entrance and photos posted on Instagram.

According to eyewitnesses, Mysterio entered the ring during an ambush by Del Rio on R-Truth, moments after Del Rio defeated The Rapping Superstar in a No Disqualification Match. The lucha libre legend reportedly connected with a 619 on the World Heavyweight Champion, and when Mr. Money in the Bank, Damien Sandow, entered the scene for a possible cash-in attempt, The Ultimate Underdog greeted him with a dropkick and another 619.

In an exclusive interview with WWE.com last week, Mysterio had indicated that he hoped to be back in the ring before the year’s end. Based on what transpired in Tupelo last night, his forecast seems very promising, indeed.
