On the night of 29 April 2017 at Wembley Stadium Anthony Joshua knocked down & defeated the Ukraine's former world heavyweight champion Vladimir Klitschko In doing so he added the WBA & IBO heavyweight titles to the IBF belt he already held That bald statement of fact does little justice to what proved to be one of the finest heavyweight contests of all time in which a brilliant but relatively inexperienced fighter took on & eventually defeated one of the finest boxers of his or any other age It was a twelve-round fight before a record post-War crowd & for eleven of those rounds it could have gone either way; indeed in Round 6 it looked as though Joshua was finished when a massive right hand from Klitschko sent him to the canvas
