TNA has updated their roster page with New TNA stars Crimson and Matt Hardy, as well as Karen Jarrett and Gunner and Murphy. http://www.tnawrestling.com/roster/superstar-roster

From this it would appear that Karen Jarrett will be back with the company for the foreseeable future. That said, Kevin Nash’s profile still remains, read into that what you will.
