Joshua laughs off Parker's drug taunts

Verbal war heating up ahead of March title showdown in Wales

LONDON - WBO heavyweight champion Joseph Parker has labelled IBF and WBA champ Anthony Joshua "the king of steroids", but Joshua doesn't seem to mind.

The two will square off in a title unification showdown in Cardiff on March 31, with Joshua, Britain's gold medalist at the 2012 Olympics, looking to add the New Zealander's name to his hit list.
