I can think of loads of Footballers turned Wrestlers or Vice versa but I can't think of any that have been in TNA.
Heindenreich? Was he in TNA?
No, but I also never said he was in TNA, I said he was in every major promotion in the US "before" his retirement. People have retired before 2002.
I shouldn't give another hint because that's technically one in and of itself, but since I'm a nice guy here you go...
1. Before retirement, I'd wrestled in every major promotion in the US.
2. I once held a tag belt with a man who considered himself a master of a specific move and fought a battle over it at a major wrestling event.
3. Aside from wrestling, I was also a pro football player.
4. I held many titles but am primarily remembered for my multiple US Title runs.
5. The son of another man who I held tag team gold with "broke" my leg in an infamous angle.
