Anthony Joshua has laughed off claims of drug use after Joseph Parker dubbed him the “king of steroids”.
Joshua and Parker will fight at Cardiff’s Principality Stadium on 31 March, the first time in history that two reigning heavyweight world champions have met in Britain.
Joshua, 28, holds the IBF and WBA belts, while New Zealander Parker is the WBO champion.
“I’ve heard so much in trash talk that nothing’s new anymore,” he said.
“I know my records are clean, that’s why I don’t bite at it.”
He added: “Trash talk has a place in boxing if it’s natural but you shouldn’t use it as a tool to sell the fight. I would never put on an act to sell a fight.”
Parker made the claim in an interview with a New Zealand radio station after the fight was confirmed on Sunday.
