Rio de Janiero: It was a tough day for the leading taekwondo fighters as none of the top-four ranked athletes in the women’s and men’s divisions made it out of the quarter-finals.

Men’s world champion and world no.1 Farzan Ashourzadeh Fallah of Iran lost in the last seconds of his preliminary match and the second-seeded Korean, Taehun Kim, was eliminated in his first fight of the day.

By the time the quarter-finals were over, the women’s double Olympic champion, China’s Jingyu Wu, and all the other top six seeds were gone.
