The 25-year-old rugby star was hit by the bus as he crossed a road in Leeds city centre during a marathon pub crawl.
Paramedics rushed to the scene where they treated Danny for concussion before taking him to hospital.
His manager James Williamson told The Sun: “Danny’s spending the night in hospital. X-rays and scans will be carried out overnight.
“He’s obviously in pain. He was running across the road and just misjudged the speed of the bus.”
An onlooker tweeted: “Every bit of the bus front window is smashed to pieces — imagine what the guy looks like.”
Danny - who was taking part in the infamous Otley Run pub crawl - has started dating 32-year-old model Kelly again after originally splitting up n 2010 after two years together.
Meanwhile, Kelly's been showing off her singing talents on video sharing site, keek.
In the clip she posted online, Kelly belts out a few seconds of Beyonce's 'Party' and we must say, she's really rather good.
