Man hit while changing tyre on Sydney road

A driver has been taken to hospital with a leg injury after being hit by a car while changing his tyre in Sydney's southwest.

The 23-year-old Harrington Park man was beside his stopped car in Narellan about 6am on Thursday when he was hit by a vehicle driven by a 26-year-old local woman.

It comes six days after a 19-year-old Sydney man was fatally struck while changing a tyre on an inside lane of a busy road in Parramatta.
