Former World No 1 Lee Chong Wei is out of the Denmark Open after going down in three games to India’s H.S. Prannoy.
The 25-year-old from Delhi needed little over an hour to secure a 21-17, 11-21, 21-19 victory and send the seventh seed packing.
After dropping the first game, Chong Wei looked to be back in business during a dominant second game, but the Malaysian’s recent run of indifferent form continued as he found himself narrowly edged out in the decider.
It’s Prannoy’s second consecutive victory over Chong Wei, following a straight-game victory at the Indonesia Open back in June.
Awaiting Prannoy in the quarter-finals is top seed Son Wan Ho, who battled past local player Anders Antonsen 20-22, 21-14, 21-18.
Others to advance to the quarters included Kidambi Srikanth, Vincent Wong Wing Ki and Rajiv Ouseph.
In the women’s draw, top seed Tai Tzu Ying battled back from a game down to defeat Thailand’s Busanan Ongbamrungphan 12-21, 21-18, 21-8.
Third seed Sung Ji Hyun also advanced after thumping qualifier Julie Dawall Jakobsen 21-6, 21-13.
She moves on to face Ratchanok Intanon, who dispatched Michelle Li in straight games.
Seventh seed He Bingjiao was knocked out, however, going down 21-17, 22-20 to Sayaka Sato.
