Since the second of those defeats by Usyk, Dubois has separated from Don Charles, linked up with Tony Sims, separated from Sims, and starting training under Charles again. Fighters are capable of overthinking and also of being impulsive – the impact of doing that might also only become clear when he and Wardley are in the ring – but it might prove relevant that both Sims and Charles spoke about liking the Wardley fight for him.
