Tour de France champion Bradley Wiggins is in hospital after being knocked off his bike.
The 32-year-old Olympic gold medal winner damaged his ribs in the collision at 18:00 GMT in Wrightington, near Wigan.
He was taken to a hospital and is being kept in for observation.
Lancashire police told BBC Sport: "He was taken to hospital with injuries that are not thought to be life-threatening. His condition is stable."
Police said the cyclist had been involved in a collision with a white Vauxhall Astra car.
"His family have made aware of what has happened. The driver of the Astra car is a local woman who was not injured but she is helping police with inquiries," a spokesman added.
The collision is thought to have taken place around a petrol station.
Garage attendant Yasmin Smith, who saw Wiggins shortly after he was knocked over, said: "Bradley was on the pavement. He actually thought he had broken his ribs.
"His hands looked bruised and they were curled up a bit. And then his colour changed. He was obviously in a lot of pain."
Wiggins, a father of two, became the first British winner of the Tour de France in July as he triumphed for Team Sky.
And weeks later he won a fourth Olympic gold medal with victory in the time trial at London 2012.
Team Sky said on their website: "We can confirm that on Wednesday evening Bradley Wiggins was involved in a road traffic accident whilst riding his bike near his home in Lancashire.
"He is being kept in hospital overnight for observation but the injuries he has sustained are not thought to be serious and he is expected to make a full and speedy recovery."
