WBA and IBF world heavyweight champion Anthony Joshua is confident Joseph Parker can successfully defend his WBO title against Hughie Fury.
Parker will be defending his title for the second time on September 24 (NZ time) in Manchester, and Joshua will be paying close attention to how the bout pans out.

The fight will be Fury's first professional since April last year, while Parker last fought in May.
If the Kiwi can successfully defend his title, then Joshua sees a potential clash between the two heavyweights in 2018.
"Parker is quite strong. Hughie can outbox him but I'm not sure how long for. Maybe Parker will stop him late on," the Englishman told The Mail.
"I'll box Parker in the future. I'm not sure about Hughie - I spoke to him a few times a few years ago but it never happened.
"I was supposed to fight Kubrat Pulev a few years ago and it never happened, so you never know.
"But Parker, I can be sure it has to happen. We have to keep the division alive."
Joshua is currently training for his next fight against Bulgarian Pulev at Millennium Stadium in Cardiff next month - which will be his first fight since beating Wladimir Klitschko earlier in the year.
