The family of a teenager from Grantham who died after being involved in a collision have described him as "one in a million".
Josh Davies, 19, was the passenger in the black Toyota Yaris which left the road and overturned in Londonthorpe last Thursday.
The driver, 20 year-old Shaun Durham, died at the scene.
Mr Davies was taken to Queens Medical Centre where he passed away on Saturday.
Police are appealing for anyone who saw the car before the collision to get in touch.
