Danny Cipriani has been released from hospital after he was hit by a bus in Leeds last night.
The Sale Sharks and former England fly-half was treated for concussion and underwent X-rays overnight, his club confirmed.
Cipriani said on Twitter: "Out of hospital now. Once again, thank you for the messages.
"Thank you for all the well wishes, means a lot. My ribs are a bit sore. Feel like I've been hit by a bus ..."
Newspaper reports claimed that 25-year-old Cipriani was on a night out with his Sale team-mates when the accident happened in the city's Woodhouse Lane area.
Sale, though, have not released any further information about events.
Cipriani was involved in a collision with a First Bus vehicle, and a spokesman for the company said: "A pedestrian suddenly ran into the road and collided with a First Bus travelling at a safe speed.
"The police have investigated this incident and have reported that First and its driver are not at fault.
"We understand the pedestrian is an England rugby international, and we wish him a speedy recovery."
Pictures taken at the scene showed the bus had a shattered windscreen.
Cipriani, who has previously played for Wasps and the Melbourne Rebels, is nearing the end of his first season with Aviva Premiership club Sale.
Among well-wishers who tweeted him today were footballer Michael Essien and Australian rugby union international James O'Connor, his former Rebels team-mate.
The Sharks, who were involved in a fight against relegation for much of this season, are now safe in English rugby 's top flight.
They have one league game left this term, at home to Wasps on May 4. It is not known at this stage how long Cipriani will be sidelined for.
Cipriani made his England debut against Wales in 2008, but after being selected for a first Test start against Scotland during that season's Six Nations he was dropped by then head coach Brian Ashton when pictures emerged of him leaving a nightclub after midnight two days before the game.
He has not featured in England colours since going on as a substitute against New Zealand during the 2008 autumn Tests.
Cipriani headed to Australian Super Rugby franchise Melbourne Rebels in 2010 before joining Sale on a three-year contract last summer.
