JOSEPH O'Brien issued a positive update on Edwulf on Wednesday morning after the horse collapsed at Cheltenham on Tuesday.
It looked like the eight-year-old was going to finish second to Tiger Roll in the JT McNamara National Hunt Chase when he went badly wrong and collapsed in the closing stages.
The final race on the card was delayed by 10 minutes as he was being treated and he was eventually moved off the course while still being looked at, before being loaded into the horse ambulance.
O'Brien is unsure what caused the gelding's collapse, but reports him to be recovering in a veterinary hospital in nearby Tewkesbury.
He told ITV4's The Opening Show: "He's in Three Counties Equine Hospital and Liam Kearns and everyone there has done a great job, and they did a great job with him yesterday on the track. It's very positive this morning.
"They're not altogether sure (what went wrong), they thought it may have been something to do with his heart, but his heart came back normal relatively quickly and then he got up.
"It's very good news this morning."
