Or at least that's what the above photo says, one he posted to his Twitter account to continue teasing he'll be joining the WWE roster as soon as possible. You can see the not so subtle reference.
There's no telling when that will be, though, and a response of his to a fan asking about the hold up is quite telling:
"If I was LEGALLY allowed to come out and say what's up, trust me, I would in a heartbeat," he tweeted. "Til then, the fans know what's up more than the 'analysts,' so that's all that matters to me."
I'm not sure about the "analysts" he's talking about but it's not hard to put together the pieces of the puzzle. He was unhappy with his treatment in TNA, so he let his contract run out. They apparently made a play to re-sign him that didn't work out and now he's headed for WWE.
The legalities he speaks of likely involve the fact that WWE and TNA are in the midst of battling it out in court over contract tampering. During the course of doing so, WWE has claimed they are not interested in any contracted talent from TNA. That no longer includes guys like Morgan and Ric Flair but it's possible the company is waiting to bring him on until the smoke clears.
In the meantime, Morgan gets to run this Twitter teaser campaign, likely pleasing his new overlords with more social media presence.
