TNA has acquired footage of Jushin Liger from New Japan Pro Wrestling and will be using it to promote his debut with the company. He'll debut at Bound for Glory.
Shannon Moore is rumored to be signing with TNA as management is interested in him. There have been many other released WWE talents who have been looking for work but are not confirmed to be debuting. Test may be the exception to that. Frankie Kazarian is also expected back soon, probably November.
Ultimo Dragon may be brought in for 'special appearance' type deal similar to Jushin Liger.
