WWE.com is reporting that Fandango suffered a concussion at last Tuesday's SmackDown taping, which is why he didn't appear at this past weekend's WWE live events.
According to the report, Fandango has passed his imPACT test, but needs to undergo further testing before he can be cleared to return.
It is unknown if Fandango will be able to face Wade Barrett and The Miz for the Intercontinental Championship this Sunday at Payback.
