Danny Cipriani left hospital black and blue on Thursday after he was hit by a bus.
The former England fly-half was treated for concussion and underwent X-rays after the incident in Leeds on Wednesday night, his club confirmed.
Cipriani, 25, was on a night out with his Sale Sharks teammates when the accident happened in the city's Woodhouse Lane area, according to reports, but Sale have not released any further information about events.
He 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."
Cipriani's agent said he "misjudged" the speed of the bus while on the Leeds pub crawl.
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.
