We reported here on WrestlingNewsWorld.com that Davey Richards specifically told me that he was signed with Ring of Honor until September 2013, despite teases he was heading to WWE.
In a further update, we're told he has already signed a "pre-deal" with WWE to begin the heath screening process. Basically the document locks a worker in, pending the outcome of the tests. WWE does this so the talent is bound but if they don't pass, they are entitled to nothing. The screening process can take time so WWE likes to get the ball rolling early.
We're also told Adam Cole has also begun the pre-screening process and is WWE bound.
