DONGGUAN - South Korea sent India crashing out of the Sudirman Cup on Wednesday as they set up a crunch quarter-final against Lee Chong Wei's Malaysia.

Nehwal beat South Korea's Bae Yeon-Ju 20-22, 21-17, 13-21 but the hard-fought win mattered little as her India team-mates were unable to capitalise.
Kashyap Parupalli went down to Son Wan-Ho and women's doubles pair Jwala Gutta and Ashwini Ponnappa lost to Chang Ye-Na and Jung Kyung-Eun, both matches going to three games.

Elsewhere Jan O Jorgensen beat Firman Abdul Kholik in the men's singles but otherwise Denmark, weakened by the cookie row, crumbled against Indonesia.
