Anthony Joshua knocks out Robert Helenius in Round 7

Anthony Joshua knocked down Robert Helenius inside seven rounds at the O2 Arena in London on Saturday.

Joshua was originally billed to fight Dillan Whyte, but that bout had to be cancelled after Whyte returned adverse analytic findings in the pre-fight anti-doping protocols.

It left Joshua looking for a replacement opponent at just a week’s notice and Helenius, moments after he had taken a three-round victory over Mika Mielonen last weekend in Finland made himself available for this fight.

After being knocked out in the first round by Deontay Wilder, Helenius was seizing an opportunity to return to action at the top tier of the heavyweight division. He began with spirit too, rushing out in the first round to cuff punches at Joshua’s guard.

Joshua, a former unified champion, is determined to reclaim a title and for him Helenius was just another step on the road back.

He was patient, he softened Helenius up with the occasional combination and then delivered a brutal ending.
