Thiago Braz, Olympic pole-vault champion and record holder, suspended for doping

Former Olympic pole vault champion Thiago Braz has been suspended after testing positive for doping, track and field authorities said Friday.

The Athletics Integrity Unit said Braz was notified of an allegation he tested positive for ostarine. No more details were published.

Braz won a surprising gold medal at the 2016 Rio de Janeiro Olympics with a jump of 6.03 meters that still stands as the Olympic record.

Braz has been provisionally suspended while the AIU prosecutes his case. He faces a ban of up to four years.

Ostarine is a selective androgen receptor modulator that can help muscle growth. It was the substance that cost the British men's 4x100-metre relay team a silver medal at the Tokyo Games after Chijindu Ujah tested positive.
