Anthony Joshua was knocked down by unknown American heavyweight Joey Dawejko in a 2019 sparring session, according to boxing coach Justin Fortune.

British star Joshua is preparing for an exciting 2021 which is likely to include a mouth-watering unification bout with British heavyweight rival Tyson Fury.

Australian trainer Fortune, who is Manny Pacquiao’s strength coach, predicted Fury would defeat Joshua due to his superior power and experience – before claiming the Watford-born boxer was dropped by the 5ft 8in Dawejko before his 2019 loss to Andy Ruiz.
