Rey Mysterio Update After WWE Star Reveals He's Undergone Surgery

Rey Mysterio experienced yet another betrayal this week on "WWE SmackDown" when Santos Escobar turned on him and seemingly the rest of the LWO. But it's going to be a while before Mysterio can respond to Escobar's actions now that the lucha libre legend finds himself on the sidelines for the foreseeable future..

This morning, Mysterio posted to Facebook that he had undergone surgery on his right knee, posting a photo of himself in a hospital bed with his right leg wrapped up. Mysterio declared that the surgery was successful, remarking that revenge against Escobar would be on the horizon.

As for the severity of the injury, Mysterio didn't specify what damage needed to be repaired nor how long the recovery would take. This isn't the first time Mysterio has encountered knee injuries throughout his career. The 49-year-old luchador has gone under the knife to deal with various issues with his left knee over the years.
