His most controversial moment came in Leicester's 1996 Pilkington Cup final defeat against Bath. As the final whistle was blown, Back pushed referee Steve Lander to the ground. Back maintained that he had mistaken Lander for Bath back-row (and future England head coach) Andy Robinson. Back was given a six-month ban from the game, but from a dark moment blazed back even fitter, fresher and more focused than he had ever been following a 20-week, 6 days a week, twice a day torturous training schedule.
