The widely held belief is that Brock Lesnar would be immediately booked into a rematch against Alistair Overeem if he decides to return to UFC. Overeem was the person that defeated him for the heavyweight championship before he decided to retire from MMA and return to WWE.
Since being released by TNA, Wes Brisco has worked a couple of shows on the independent wrestling circuit, and it appears that he is hoping to expand his horizon by working overseas. He already has a connection to New Japan through Luke Gallows, his former Aces and Eights teammate.
In a move that has been speculated for quite some time now, it appears that TNA has indeed released second generate star and former Aces and Eights member Wes Brisco. His profile has been removed from the official roster page on the company website.
