Wrestlemania 31 will be an exclusive WWE event next year, as Vince McMahon has secured deals with venues in Santa Clara to not allow other wrestling promotions to run shows in the area during that weekend. Other companies have been feeding off of the influx of wrestling fans over the years.
Mike Knox could be the next person headed out the door in TNA. While the company likes him, they simply do not have anything planned for him since the split of Aces and Eights. There is a possibility of him being brought back into the fold at a later time.
