Via his Twitter page, Yoshihiro Tajiri announced that he would be leaving WWE. He returned to the company in early 2017, but noted that he suffered a knee injury of undisclosed nature. While he recovered he tried coaching in NXT, but the injury was enough that at his age (46) he elected to move on. He noted in the tweet that he would be returning to Japan and thanked the company for the opportunity.
