Oscar Valdez is keeping his title…

The 30-year-old Mexican boxer retained his WBC super-featherweight title with a unanimous points victory over Brazil’s Robson Conceicao.

Valdez had been cleared to fight despite failing a drug test.

Judges at Casino del Sol in Tucson, Arizona, awarded the fight to Valdez 117-110, 115-112, 115-112.

Former Olympic champion Conceicao, 32, took the fight to the man he had beaten as an amateur and started the stronger.

But as he tired, Valdez started to take the upper hand and judges decided he had done enough to win.

Some have questioned whether the fight should have gone ahead at all after Valdez failed a test for the banned substance phentermine, a weight-loss drug, but was cleared to fight by a gaming commission.

Valdez insisted he was a clean fighter and believed he had accidentally ingested it via an herbal tea, while WBC president Mauricio Sulaiman said phentermine was not a performance enhancer.
