GLASGOW, Scotland (AP) – The Commonwealth Games Federation says Nigerian female weightlifting gold medalist Chika Amalaha has failed a doping test.

CGF chief executive Mike Hooper says Tuesday that Amalaha tested positive for diuretics and masking agents after winning gold in the 53-kilogram (117-pound) division last Friday.

The backup “B” sample will be tested on Wednesday.
