Indian shuttler HS Prannoy moved into the men's singles pre-quarterfinals of the Japan Open after his opponent Ng ka Long Angus retired hurt midway in the first round here on Tuesday.
The unseeded Prannoy was narrowly leading the first game 11-10 when the world number 12 player from Hong Kong threw in the towel within seven minutes of their men's singles opener.
The world number 18 Indian will now take on former world champion Loh Kean Yew of Singapore in the second round.
Prannoy had been in fine form at the BWF World Championships in Tokyo last week, stunning two-time world champion Kento Momota before getting the better of compatriot and Commonwealth Games gold medallist Lakshya Sen.
However, his stellar run ended in the quarterfinals as he lost to China's Zhao Junpeng.
In women's doubles, India's Ashwini Bhat and Shikha Gautam lost 15-21, 9-21 against Korea's Yu Lim Lee and Ha Na Baek in the round of 32.
There were just two matches featuring Indians on Tuesday. On Wednesday, though, the likes of Lakshya Sen, Srikanth Kidambi, Saina Nehwal and Dhruv-Kapila-MR Arjun will begin their campaigns.
