UPDATE x 6: Kurt Angle’s TNA contract has officially expired and according to sources, he’s now a free agent. Angle has reportedly had talks with WWE about a return as we've noted in recent months.
Angle is telling people close to him that WWE offered him a full-time deal (assuming he could pass a medical test) but he turned it down. Angle claims he doesn't think his body would be able to handle a full-time schedule. Instead, he had the idea of a part-time deal. According to him, negotiations are still ongoing. Other sources say this is just "Kurt being Kurt" and that WWE has no interest in him due to the risks involved.
Angle is also said to be willing to return to TNA if they come to terms on a new deal. He credits Dixie Carter and the company for helping him when he had his personal issues over the years. He debuted for TNA in September 2006 as a surprise. It was several months after his WWE release. Prior to his TNA debut, there had been rumors that he was retiring.
UPDATE x 5: Mark Madden recently interviewed TNA wrestler Kurt Angle on 105.9 the X. Angle promoted TNA's upcoming event in Washington, Pennsylvania set for August 16.
So WWE offered Chris Jericho and RVD part time contracts, but they offered Angle who's older and in worse shape from a medical standpoint a full time contract
