Lee Zii Jia crashed out in the opening round of the French Open after a 19-21, 18-21 defeat against Shesar Hiren Rhustavito on Wednesday, with the shuttler playing through a personal loss.
Lee is understood to have lost his grandfather, who passed away while the shuttler was in Paris for the Super 750 event.
That agony showed as the Denmark Open number runner-up did not look as sharp against the Indonesian, who also beat him at the Malaysia Open, and threw his racquet in frustration after the 44-minute loss.
Fans later took to social media to send their condolences to the shuttler.
All in all, it was a day to forget for the Malaysian contingent as everyone except Goh Sze Fei-Nur Izzuddin also crashed out on Wednesday.
They included Goh Soon Huat-Shevon Lai, Hoo Pang Ron-Toh Ee Wei, Aaron Chia-Soh Wooi Yik, Vivian Hoo-Lim Chiew Sien, Tan Wee Kiong-Tan Kian Meng and Liew Daren.
But there are several national shuttlers still left in the mix for Thursday's action, including women's doubles pair Pearly Tan-M. Thinaah who take on Febriana Dwipuji-Amalia Cahaya.
In the men's doubles, Man Wei Chong-Tee Kai Wun are up against Satwiksairaj Rankireddy-Chirag Shetty, while Ong Yew Sin-Teo Ee Yi and Sze Fei-Izzuddin are up against Indonesian opponents in Leo Rolly Carnando-Daniel Marthin and Muhammd Shohibul Fikri-Bagas Maulana.
The mixed doubles see Tan Kian Meng-Lai Pei Jing play Japanese pair Yuki Kaneko-Misaki Matsutomo.
