The former World no.1 and star Indian shuttler Saina Nehwal exited the Swiss Open after losing her women's singles second round to lower-ranked Kisona Selvaduray of Malaysia.
The 23rd-ranked Indian could not maintain the consistency she showed in the first game to lose 21-17, 13-21, 13-21 against her 64th-ranked opponent on Thursday night.
Earlier, four Indian shuttlers including double Olympic medallist P V Sindhu and World Championships silver winner Kidambi Srikanth, progressed to the quarterfinals of the Swiss Open badminton tournament on Thursday.
While Sindhu, a former world champion, eased into the last 8 with a 21-19, 21-14 win over Neslihan Yigit of Turkey, Srikanth staved off a spirited challenge from France's Christo Popov, ranked 60th, with a fighting 13-21, 25-23, 21-11 win in the Super 300 tournament.
Second seed Sindhu will square off against either fifth seed Canada's Michelle Li or Denmark's Line Christophersen. Seventh seeded Srikanth, who had missed India leg of the BWF tour in January after testing positive for Covid-19, will face second seeded Dane Anders Antonsen next.
Former top 10 player HS Prannoy also struggled past Finland's Kalle Kolionen 19-21, 21-13, 21-9 to find a place in the quarters as did former Commonwealth Games gold medallist Parupalli Kashyap after top seed and Olympic champion Viktor Axelsen gave a walkover.

On Wednesday night, Sindhu had entered the second round with a 21-14, 21-12 win over Denmark's Line Hojmark Kjaersfeldt here. Sindhu, also a former world champion, will face Neslihan Yigit of Turkey late in the day.
