However, on the 29 September episode of NXT, the night Rook was scheduled to face NXT Champion Grayson Waller for the title, it was reported that Rook had not been medically cleared to compete and would be out for the “foreseeable future”. He would be replaced by EK Prosper, who answered Waller’s open challenge.
