Daryl Jacob was taken to hospital for further investigation following a fall from Caribean Boy in the Howden Silver Cup Handicap Chase at Ascot.
The jockey took a tumble from the Nicky Henderson-trained seven-year-old at the first fence in the three-mile contest. He was treated at the scene before being taken by ambulance from the Berkshire course.
“Daryl suffered a fall in the Silver Cup and he’s gone with a suspected bone injury, a possible leg or hip injury,” said clerk of the course Chris Stickels.
“He’s gone for X-rays to Wexham Hospital in Slough.
“He was conscious and talking.”
Jacob gave an update on his condition on his official Twitter account on Saturday evening: “Thank you for all the kind messages. I’ll be leaving hospital shortly. I’m battered, bruised and very sore but I’ve still got my looks! I’ll know more in the next couple of days, but safe to say, I won’t be at Fakenham tomorrow!”
