Badminton world number one Kento Momota was injured and his driver was killed in a crash near Kuala Lumpur on Monday just hours after he won the Malaysia Masters.
Police said the Japanese star, 25, suffered a broken nose and cuts to his face when the van carrying him to the city's airport crashed early in the morning, in a blow to his preparations for this year's Tokyo Olympics.
The driver was killed at the scene after the vehicle collided with a slow-moving lorry on a highway. An assistant coach, physiotherapist, and badminton official also suffered minor injuries.
The accident came after the dominant Japanese star began his 2020 season in style Sunday with victory over Denmark's Viktor Axelsen in Kuala Lumpur.
"It's truly tragic, especially involving a badminton icon like Momota," Malaysian sports minister Syed Saddiq told reporters, after visiting the injured in hospital south of the capital. But he added those hurt were "recovering well, (and) all four are also in stable condition".
The others hurt suffered facial, leg, hand and head injuries, according to the police.
The Badminton Association of Malaysia said in a statement they were "saddened" by the crash.
The accident happened around 4:40 am (2040 GMT Sunday), and 10 firefighters rushed to the scene, senior fire and rescue department official Norazam Khamis told AFP.
Pictures showed the front of the van crushed against a lorry but the back section appeared intact.
Momota enjoyed a stellar 2019, winning a record 11 titles including the World Championships, Asia Championships and All England Open, a turnaround for a player who had been banned for gambling in 2016.
