From TNA's website:
TNA IMPACT WRESTLING announces Lex Luger to be one of the featured guests as part of the inaugural TNA Hall Of Fame Celebration inducting "The Icon" Sting. The TNA Hall Of Fame Celebration will be held Saturday, Oct. 13 at the Pointe Hilton Tapatio Cliffs Resort at 8pm local time and will profile the iconic career of Sting. Featured guests include Hulk Hogan, Dixie Carter, AJ Styles, Mike Tenay and Lex Luger.
Multi-time World Champion Luger is a long-time friend to "The Icon" Sting. Even in fierce competition the two remained friends while competing against each other in multiple championship matches.
Thoughts? I think this is a pretty good choice since Flair's not available.
