Willie Mullins hopes to be able to run a series of tests on former Champion Hurdle hero Faugheen at the Liverpool Equine Hospital.
The multiple Grade One winner was found to have a fibrillating heart in a post-race examination after pulling up mid-race in the Aintree Hurdle at the Merseyside track on Thursday.
Mullins said on Friday afternoon: “He was grand last night. I will probably try to get him to the equine hospital in Liverpool for some tests.
“Otherwise he will go home, if they are unable to check him we will go home and check him out there. Hopefully it will have settled down.
“It can correct itself in a few days. If it doesn’t there are ways of correcting it. It is not a complicated thing from what I can gather. It is a regular enough occurrence.”
