Wayward King faces a crucial 24 hours after sustaining a serious leg injury at Kempton on Saturday.
Ron Hodges's stable star suffered the damage to his off-fore when he was caught by the flailing leg of Macgorge when that horse fell at fifth-last fence in the Racing Post Chase.
Wayward King remained overnight at Kempton where he is receiving veterinary attention.
Hodges, speaking from his Somerset stable this morning, said: "We X-rayed him last night and he was very distressed.
"We could find no fractures on the plates, and it looks like he has pulled all the muscles and ligaments and the nerves between the knee and the elbow. It has left him with a paralysed leg. The vet is doing another X-ray this morning.
"They are going to leave it another 24 hours and see what we've got but it doesn't look at all good. But we shall do all we can to save the horse obviously.
"It was no fault of his own. The other horse hit him as he was falling, and one of his legs has hit ours.
"That is what Joe Tizzard seemed to think happened. Then Joe lost an iron and by the time he got it back he was in to the next fence and he had no option but to jump it."
Wayward King went into the Racing Post Chase on a hat-trick and Hodges feels the eight-year-old would have been placed behind Gloria Victis but for his accident.
The trainer said: "He was travelling very well. He wouldn't have beaten the winner but he'd have definitely been in the frame and I felt he was going as well if not better than Marlborough at the time."
Macgeorge escaped with nothing more than a cut following the incident.
Richard Lee's horse took a heavy fall at the fifth fence from home in the Racing Post Chase and in doing so made inadvertent contact with Wayward King.
Carol Lee, the trainer's wife, reported: "He seems fine. He's been out in the field this morning and had a pick of grass. He wasn't even that stiff.
"He's got a bit of filling in his near hind where he's cut himself but he has escaped pretty amazingly really.
"I'm sorry to hear about the other horse. That is bad news. We've come through fairly luckily in that case."
Macgeorge is engaged in both the Tote Cheltenham Gold Cup and the William Hill National Hunt Handicap Chase at the Festival next month and Mrs Lee said: "We have to take him to Cheltenham, where he's actually always runs quite well.
"We have no other options. There are just aren't enough races for these decent three-milers on the good tracks."
