A decision on the future of Harbinger will be made tomorrow.
The brilliant winner of the King George VI and Queen Elizabeth Stakes fractured his near-fore cannon bone during a routine spin on the gallops in Newmarket on Saturday.
Although subsequent surgery has been a success, his racing career remains in the balance.
John Warren, director of Highclere Thoroughbred Racing, who own the colt. said: "The horse is very comfortable and the cast that was put on his leg to help him get up after surgery has been taken off.
"He's eating up well and has a very good demeanour about him, so it is a very good report about his well-being, which is a great relief.
"We plan to have a discussion with all the shareholders in the next 24 hours and then a decision about his future will be made tomorrow. After consultation with all concerned, we will make a statement."
