The man killed in an alleged road rage attack in Sydney's west has been identified as an amateur kickboxer.
Rhyce Harding, 27, died after he was allegedly dragged 100 metres by a ute along Jersey Road in Blackett about 8.45am yesterday.
Police allege he had got out of his vehicle after being threatened by the car following him and "words were exchanged".

"It's devastating and bad for the victim's family," Inspector Shane Ranee said at a press conference yesterday.
Harding was a kickboxer who had trained tirelessly and notched his first amateur win this time last year.
His family have not yet commented on his death.
The man behind the wheel of the ute left the scene yesterday, prompting an almost 24-hour search for him and a police appeal for information.
