Although very unlikely, if Shawn Michaels would go to TNA, would he be allowed to use the name 'Shawn Michaels' and HBK?
No, HBK has to much love for the WWE and the WWE fans, although that was the same thing that Ric Flair said and look at him now, But I'm Shawn is a different story, so I don't think that he will end up in TNA. I think he might return to the WWE in the near future.
I think that HBK is own by WWE, But other than that Shawn Michaels could be used in any wrestling industry(Correct me if i'm wrong).
