There are talks that Sting could possibly be leaving TNA, as the company has set up a farewell scenario next week on the second part of Genesis. His contract had actually expired at the end of December, but the WCW legend opted to stick around for a little while longer.
Usually, when a performer informs WWE that they are leaving, it becomes a well known fact within the locker room, but in regards to Kaitlyn stepping away from the company, very few people were notified ahead of time, so it came as a surprise to most people.
Another name on the chopping block in TNA right now is Garett Bischoff, who has not really done much in the company since management decided to split up the Aces and Eights stable. His father, Eric Bischoff, recently scaled back on his duties within TNA.
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.
