Details regarding Rook’s injury are unknown at this writing. The NXT rookie last wrestled on September 19 at a live event in Fort Pierce, Florida, where Birthright defeated him, Hank Walker and Tank Ledger in a six-man tag team match. Days later, he appeared on NXT and cut a back-and-forth promo with Waller in the ring.
Rook was given a chance to face Waller, winning first for himself, Saquon Sugars and Tony D’Angelo. When the three faced off in a triple threat the following week, Rook splashed D’Angelo and then pinned him.
Waller captured the NXT Championship last month by winning a fatal four match involving himself, D’Angelo, Zilla Fatu and Cruz Montana at last month’s NXT Heatwave Premium Live.
