With internal pressures mounting in the club following the 1967–68 season however, Stock was absent for three months, suffering from asthma. In his book "A Little Thing Called Pride" Stock tells how Jim Gregory sacked him in 1968 for being ill, just as he thought he was about to return to the helm and save Rangers from relegation. He later had success with Luton Town who he helped to promotion from the Third Division and also with Fulham when he led them to the 1975 FA Cup Final. He briefly returned to be a Director at Queens Park Rangers in the 1977/8 season.
