• British heavyweight was due to defend title on Saturday
• Martin Bakole steps in to face Parker as replacement

Daniel Dubois has withdrawn from his IBF world heavyweight title defence against Joseph Parker on Saturday after falling ill.

The British boxer was evaluated by a doctor on Thursday, according to a report in the Ring magazine, but is unable to compete. The 27-year-old will be replaced by heavyweight contender Martin Bakole, a dangerous proposition for Parker on short notice.
