The Commonwealth Games Federation this morning July 29th said Nigerian female weightlifting gold medalist Chika Amalaha has failed a doping test.

CGF chief executive Mike Hooper said Amalaha, 17, tested positive for diuretics and masking agents after winning gold in the 53-kilogram (117-pound) division last Friday July 25th.

The backup “B” sample will be tested tomorrow Wednesday July 30th.
