Anthony Joshua faces the dark side of Sports: undergoes early morning drug test

With Anthony Joshua, the  World Heavy Weight Champion still basking in the euphoria of his win over Wladamir Klitschko and planning his next move, the dark side of being a sportsman may just be  enough to jolt him out his bubble.

The boxer received unexpected guests  at his home early hours Thursday morning, carry kits to conduct a drug test on him.

The drug testers stormed the  Olympic gold medalist home at 7am.

The IBF and WBA 'super' heavyweight champion of the world is plotting his next move, having secured a stunning stoppage win over 'Dr Steelhammer' at Wembley last month.

Victory propelled Joshua to boxing super-stardom and put the 27-year-old on course for more big fights under the lights.

Heavyweight boxing has been rocked by a number of recent failed drugs tests, with both Alexander Povetkin and Andrzej Wawrzyk testing positive in the lead up to fights with WBC champion Deontay Wilder in the last couple of years
