Sprinter Sacre pleased Nicky Henderson and heart specialist Celia Marr when cantering at Seven Barrows on Friday morning.
Marr told Racing UK she was "optimistic" for the horse's future. "It's too early to say, but it's perfectly possible that this doesn't trouble him again. Even if it does come back, it can be years down the line. "There are a lot of factors that come into play here, but if you self-correct as Sprinter Sacre has done, you can come back fairly quickly. You just have to be cautious and build up his work slowly and monitor the horse carefully. "I'm certainly optimistic that he'll be racing again, but you're not going to pin me down to when."
