It appears as though the WWE has given the old "future endeavors" to Alvin Burke, aka Hassan Hamin Assad, aka Montel Vontavius Porter, aka MVP.
Not a big fan of releasing him. I think MVP still had a lot to offer to the midcard of the WWE. Now, THIS is someone that TNA definitely should pick up.
That being said, I can't really claim to be incredibly surprised. He's been airing his frustrations on Twitter the past few weeks and indicating that he would be leaving. In fact, the other day even, Jericho asked him if he's still in the company and he responded "If you find out let me know please! Lol"
They may have been angry at the fact that he was doing this on a public forum, they may have just thought that he outlived his usefulness, or hey, maybe even he quit. Right now, its just speculation.
