Luke Harper posted this on Twitter today:
As of this evening, I have requested a release from WWE. The past 6 years have been a simply, amazing journey around the world and back with lifelong friends and family. I am proud of it all and proud to say I shared the ring with my co workers.
This decision, as difficult as it was, feels right for myself and WWE. My goal in the future is to continue to grow as a performer and person and continue to make my family proud.
Thank you. From the top to the bottom of WWE. Thank you to the fans for your undying support. Thank you everyone.

WWE has not granted him the release (yet), according to Dave Meltzer.
Harper has been off of Raw and SmackDown since August when his partner Rowan underwent surgery for a torn bicep. While Rowan was out, Harper also had surgery on his wrist. He returned to the ring at a house show in March and briefly wrestled in the Andre the Giant Memorial Battle Royal at WrestleMania.
