Rey Mysterio Out Until WrestleMania XXIII

Rey Mysterio announced Monday on Twitter that he will be undergoing surgery this Friday after sustaining an injury to his knee. The masked performer blew his knee, believed to be his ACL, while attempting a baseball slide during his match against Alberto Del Rio on last week's episode of Raw. 

There is talk that he may not be able to return to action until WrestleMania XXIII.
