Bully Ray (or Bubba Ray Dudley) has made it clear on his verified Twitter account that he worked last Friday’s Impact Wrestling on a per shot deal and is not back under contract with TNA.
Based on his activity, it’s certainly not hard to assume that Ray would welcome a return to WWE if they called him. Ray has interacted with fans that have called for a Dudley Boyz reunion in WWE and even said it would be fun to face Kevin Owens in a singles match.
Ray returned to WWE as a surprise Royal Rumble entrant back in January as Bubba Ray Dudley.
Wrestling News World broke the news of Bully Ray returning to TNA as the special guest referee of Kurt Angle vs. Eric Young at this link.
