UPDATED: According to f4wonline.com, Rey Mysterio will not be attending the TripleMania event on Sunday. Mysterio is still under a WWE contract, and WWE would not want him attending the show as it will be in direct competition on Sunday with Summerslam. 

ORIGINAL: According to Steve Sims at F4WOnline.com, here is the latest on Rey Mysterio. During a recent edition of Figure Four Weekly, Sims noted that Mysterio had been invited to Sunday's TripleMania event. At this time, it is only a scheduled appearance, and he is not expected to wrestle. Mysterio is looking to get out of WWE, but as previously reported, WWE feels that he owes them a year because of the time he's been off due to injuries. Mysterio is still a WWE employee, but rumors are that he stopped cashing his WWE checks, and there were rumblings that the situation could potentially become a legal issue.
