Anthony Joshua will fight Robert Helenius on short notice tonight, after the Briton’s rematch with Dillian Whyte collapsed due to an adverse drug-test finding. Joshua knocked out Whyte in 2015, avenging an amateur loss to his compatriot, and the old rivals were due to square off again this week. However, Whyte failed an anti-doping test, causing the bout to be called off. Now in comes Helenius, saving the weekend’s event as the Finn competes for the second time in seven days. Helenius, 39, beat Mika Mielonen in the third round last week, in what might have been a useful warm-up for his clash with “AJ”. • Get all the latest boxing betting sites offers Meanwhile, 33-year-old Joshua last fought in April, beating Jermaine Franklin on points to bounce back from two straight losses to Oleksandr Usyk. Joshua’s rematch with Whyte was meant to be the next step on the road to a fight with Deontay Wilder, and that contest is still in the works for early 2024. Here’s all you need to know.
