Saina skips Singapore Superseries for Asia Championships preparation

"Yes, I withdrew from the tournament as I feel I need some more time training to get better. There is improvement in the knee but I think some more training will help at this point," Saina told PTI. "I will play Asia Badminton Championship next. I will also play the Indonesia Super Series and Sudirman cup," the London Olympics bronze medallist added.

Saina lost to Japan's Akane Yamaguchi in the first round of the Malaysia Open earlier this month.  Meanwhile, PV Sindhu is drawn to play Japan's Nozomi Okuhara first in the Singapore event. Sindhu clinched her maiden Indian Open this season that saw her rise to No 2 in the world rankings.

Ajay Jayaram, who beat world No 2 Viktor Axelsen en route to the quarterfinals at the Malaysia Open, will open against fifth-seeded Chinese Shi Yuqi, runner-up at All-England.

Kidambi Srikanth will look to make a winning return to competitive action after skipping the Malaysia Open.
