Haas took shots at Delirious and Kevin Kelly during the promos "for all the things they say" about him and called Kelly a "fat piece of shit." He was reportedly shaking and cried during the match as well as later in the locker room; he changed and left quickly after he was done. There were people legitimately concerned about his well being.
Haas later tweeted:
Officially retired. No match against [Shelton Benjamin] next week NYC. Time to be a full time dad and husband. I've turned my spandex in for scrubs. Thanks to all the fans throughout the years. I love you all. Stay safe and God bless. WGTT will always be a top Tag Team, forever.
All signs point to this being legitimate and not part of an angle.
