Whatever happens in the Cardiff ring next month as Anthony Joshua and Joseph Parker attempt to claim what both believe is their destiny in unifying the heavyweight world titles, it should be a fair fight because both will have undergone a thorough testing regime for illegal drugs.
Kiwi Parker and Englishman Joshua have signed up to Voluntary Anti-Doping Agency (VADA) protocols, which means they can have their blood and urine tested at regular intervals before the March 31 fight.
Parker's promoter David Higgins told the Herald on Sunday: "I can confirm Joseph Parker has been tested three times and Anthony Joshua has been tested four times."
This is significant for the credibility of the event, expected to be the richest in British boxing history, and for the fact Joshua was described by Parker recently as being the "king of steroids", a jibe which Higgins described as a "throwaway line" and which he and Team Parker have since backed away from.
Parker, too, made headlines last year when he wasn't at his Las Vegas home when drugs testers arrived following his victory over Razvan Cojanu in Auckland in May.
