Anthony Joshua will face a different kind of test this weekend, fighting Robert Helenius on short notice in London. Joshua, 33, was set to take on Dillian Whyte this week, in a rematch eight years in the making, but Whyte returned an adverse finding in a drug test on Saturday. As a result, he lost his chance to avenge his knockout loss to Joshua, who will now fight Helenius at the O2 Arena. Helenius, 39, fought just last week, stopping Mika Mielonen in Round 3. With that win, the Finn bounced back from a knockout loss to Deontay Wilder. Meanwhile, Briton Joshua last fought in April, beating Jermaine Franklin on points after suffering two straight losses to Oleksandr Usyk. Here’s all you need to know.
