Robert Helenius failed a pre-fight drugs test prior to his recent heavyweight fight with former world champion Anthony Joshua, it has been revealed.

The 39-year-old Finn, knocked out by Joshua in the seventh round at London’s O2 Arena on August 12, had stepped in as a late replacement for Dillian Whyte, who had failed a drugs test himself.
