Joseph Parker says he will bring more aggression and action to his key clash with Dillian Whyte this Sunday.

The New Zealand boxer, who trains in Las Vegas, intends to be on the front foot more than he was in March’s points defeat to Anthony Joshua, which cost him his WBO world heavyweight title.

Parker can put himself back in contention for a possible rematch with WBA–IBF–WBO world heavyweight champion Joshua next year if he defeats Whyte at the O2 Arena in London.

The outcome of Sunday’s clash has huge implications for both fighters. A win would propel the victor to a potential world title fight against Anthony Joshua or Deontay Wilder while a defeat could end their career on the big stage.
