It has been confirmed that Randy Orton did not attend Monday's RAW because he is dealing with soreness in his neck. He has been pulled from live events this weekend and next weekend. He had an MRI done on his neck this week to determine why it's been giving him problems. As reported earlier it's the reason he wasn't on Raw and was pulled from on house shows.
Goldust has had an MRI on his shoulder and is now waiting on results.
Orton is a major part of Raw right now and with so many guys getting injured they don't need another.
Same goes for Goldust especially since he was just coming back into his own following that feud with Teddy D.
