Lee Zii Jia retired for a second consecutive match as he conceded his opening round encounter against Rasmus Gemke at the Indonesia Masters.

Lee’s participation had been in doubt after he retired in the Hylo Open final against Singapore’s Loh Kean Yew.

The world number seven had clearly not recovered, as he retired after just 13 minutes while trailing 9-11.

Men's singles chief Hendrawan later said Lee's hip injury had not completely healed.

"He is still experiencing pain and we are not going to force him to play. We will continue to monitor his situation ahead of next week's tournament," he said.

Several national shuttlers were in action on the opening day of this Super 750 event with mixed results.

In the mixed doubles, Hoo Pang Ron-Cheah Yee see progressed to the next round after their opponents Yujiro Nishikawa-Saori Ozaki retired within the first five points of the opening game.

Chen Tang Jie-Peck Yen Wei did well to beat South Koreans Seo Seung-jae-Kim Hye-jeong 21-17, 21-13, but face a tough second round assignment when they meet top seeds Dechapol Puavaranukroh-Sapsiree Taerattanachai.

The biggest disappointment came from senior pair Chan Peng Soon-Goh Liu Ying, who once again succumbed to an early round defeat of 13-21, 19-21 to German pair Jones Ralfy Jansen-Linda Efler.

Jansen-Efler, who meet Hoo-Cheah in the next round, needed 42 minutes for the win to once again highlight the downward spiral of the Malaysians.

Since the Tokyo Olympics where they lost all their matches, Chan-Goh lost three of their opening round matches, with only a quarter-final appearance at the French Open to show as their best recent result.

In the men’s doubles, it was also the end for Goh V Shem-Low Juan Shen who were upstaged 21-18, 21-18 by French pair Lucas Corvee-Ronan Labar.

Ong Yew Sin-Teo Ee Yi did well to beat India’s Satwiksairaj Rankireddy-Chirag Shetty 21-17, 21-15, while Sze Fei-Nur Izzuddin also won their match against Kang Min-hyuk-Seo Seung-jae 21-10, 21-17 and next face Muhammad Shohibul Fikri-Bagas Maulana.
