The American, currently in preparations to face Luis Ortiz next week, is hoping to land the winner later in the year with all five title belts on the line.
Ahead of his own defense and a scheduled trip to the UK for Joshua v Parker commentary duties, Wilder is adamant an early knockout is not on the cards.
“I’ve always said ‘later rounds’. I see that fight going later rounds if Joseph Parker is smart in what he does,” he said.
“He has nice movement and is able to execute on all of the opportunities that he sees with Joshua.
“Because Joshua can’t move his head. He’s a muscle, body-building type of guy. You’ve seen my dance? [chuckles] With that, if he’s able to calculate what he needs to do in the ring – because the ring has a lot of secrets – if he’s able to do things he needs to do, I see late rounds.
“But, like I said before, I think they’re going to have to knock Joshua out because they’re not going to give it to him,” added Wilder.
‘The Bronze Bomber’ has been chasing a battle with Joshua for over two years since landing the coveted green and gold belt against Bermane Stiverne.
Joshua’s promoter Eddie Hearn seems to be suggesting fights with Alexander Povetkin and Jarrel Miller could be in the Briton’s future, moves which could further test Wilder’s patience.
A huge collision for all the marbles in Las Vegas this December is the hopeful scenario, with a summer return at Wembley Stadium in 2019 dependent on the initial result.
