Kurt Angle is currently in the process of brokering a deal between Brock Lesnar and TNA. Brock has already met with Dixie Carter, but Angle has a good history of man*pulating him, as he did with their match in Japan a few weeks ago.
Lesnar, now 265 pounds, and not near the physical looking monster he was in WWE, is not wanting to hurt his body and still really wants to work MMA (as noted earlier he was at UFC’s Respect last week). Angle is trying to convince him that he will be able to run his own schedule, make a good income, and have far less travel than what WWE required.
TNA is willing to give him time off to train for MMA fights, but the way things are going now, it’s really not something you can do part time.
