According to PWInsider.com, the reason why Rey Mysterio has been removed from WWE house show events in recent weeks is due to an ongoing family manner that has caused Mysterio to need to take time off and remain at home. It is said that there has been no issue from the WWE from Mysterio needing the time off and they are doing their best to accommodate him. As reported earlier, Randy Orton will be replacing Mysterio on an upcoming tour of Puerto Rico.
