“I am ready to go. I have put all the hard work with my team in Ireland, my team here in Riyadh.”
Parker attended the press conference alongside his manager, Spencer Brown, who said that his team was in “many discussions.”
Brown added: “Joe will be there on Saturday, whatever happens and he is ready to win. Joe does not care about those who fight.”
