When Barbarian and Warlord left the NWA while in the midst of a high profile feud against the Road Warriors, a lot of people were puzzled. It was later discovered that the Powers of Pain had backstage heat with the company because they did not want to work a series of scaffold matches.
In 1986, the Warlord started working out at a new gym when he was approached by the owner, better known to wrestling fans as Road Warrior Animal, about a possible career change. Animal sent him to Dusty Rhodes, and a contract with the NWA shortly followed.
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.
Back when both of them were working for UPW in 2000, Mike Knox and Samoa Joe were tag team partners.
