This weekend’s heavyweight bout between Anthony Joshua and Robert Helenius in London is heavily favored to be won by Joshua.

At the O2 Arena in April, AJ defeated American heavyweight Jermaine Franklin by majority decision, bringing his career record up to 25-3.

In a highly anticipated rematch, he was supposed to face Dillian Whyte on Saturday, but Whyte failed a random doping test last week.

Eddie Hearn, the promoter, hastily tried to locate a last-minute substitute, and Helenius has volunteered.

Obviously, he hasn’t had much time to train for this bout, which greatly disadvantages him. With a 32-4 professional record, Helenius is still a formidable foe, so Joshua cannot afford to underestimate him on Saturday.

There was word that Joshua was looking for a successor since Whyte had withdrawn and Helenius had been selected as the front-runner.
