WWE.com is reporting the following:
At Tuesday nights SmackDown television taping, Mr. Money in the Bank Randy Orton was injured during his match against World Heavyweight Champion Alberto Del Rio.
According to WWE medical personnel, the nine-time World Champion suffered a cervical strain and cervical neuropraxia.
I know the no posting spoilers from smackdown, but WWE.com has reported this, so I'm assuming this doesn't count.
Tried discussing this on the comments on the story, but too many people there have zero idea what the injury actually is.
Cervical neuropraxia is simply what is called a "stinger" or "burner" to anyone who's played football, rugby, or has wrestled. It is not what caused Austin or Edge to retire, it requires no surgery, and generally won't require any missed time.
People seem to be confusing cervical neuropraxia and spinal stenosis. Spinal Stenosis is what caused Edge and Austin to retire. Spinal Stenosis is the narrowing of the spinal column which puts pressure on the spinal cord and can lead to paralysis.
That being said, until Orton is checked out tomorrow, it will not be possible to rule out a more severe injury that could have masked itself as a stinger. Despite what numerous people on the comments claimed, it is possible to diagnose a stinger without an MRI or Xray as it's done quite often on the football field when it happens.

That link has an excellent article about stingers and other sports related spinal injuries.
If Orton indeed simply suffered cervical neuropraxia with no stenosis, he might miss the rest of the house shows this week but shouldn't miss any television or ppvs.
