"WWE NXT" star Mason Rook made his return to the WWE Performance Center on Tuesday's edition of the developmental brand, and his sights are once again set on the NXT Championship. The star took to the ring in the opening segment, working alongside Shiloh Hill to beat down Grayson Waller.Following his return, Rook posted to X (formerly Twitter) to vaguely discuss what kept him on the shelf for nearly two months. It was previously reported the star would be out for "the foreseeable future.""Only a select few know the severity of what I've come back from," Rook posted, quoting WWE's video of his backstage interview. "I worked my a** off to get back ahead of schedule. "Strap in, because I'm gonna cause a Rookus"It was revealed Rook would be out of action the day he was set to take on Waller for the NXT Championship on the September 29 edition of "NXT." Waller would go on to successfully defend the gold against EK Prosper that night. On the most recent episode of "NXT," Waller was challenged by a serious Hill and rejected the match before he was beaten down by the returning Rook.Bryan Alvarez said on the October 7 edition of "Wrestling Observer Live" that he was told whatever Rook was dealing with could have kept him out for a "very long time." He stressed, however, that he didn't know the nature of Rook's injury, and he noted no one seemed to be talking about what it was. Rook himself has yet to specifically address what had been ailing him.
