5 former superstars who may never return to WWE

#2 Former WWE Superstar Nailz

In the world of '90s WWE, where occupational gimmicks were prominent, Nailz was introduced as the victim of The Big Boss Man. Nailz's career in the company proved to be short after the man behind the gimmick allegedly choked Vince McMahon over a monetary conflict, an incident that has been confirmed by the likes of Bret "The Hitman" Hart.

Don't expect Nailz to return to the company at a reunion themed show anytime soon. His violent attack on McMahon practically sealed the deal, but he even testified against the latter in court during the highly publicized steroid scandal, claiming that McMahon asked him to use steroids.

#1 Former WWE Hardcore Champion Chris Nowinski

Chris Nowinski's career as a professional wrestler may have been unmemorable, but he has more than made up for it with his next career path as an author and neuroscientist. Nowinski has attacked the very core of the company's working structure and has vaulted CTE into a subject of international discussion.

While he has not criticized WWE on every occasion, his research and comments hardly run parallel to the company's public presentation of its treatment of performers. Thus, a return of Nowinski to the company will probably never take place, with neither side interested in making it possible.
