Aiming for the Irish St Leger, he hopes to return to his best in the Group Two contest for Cheltenham-legend Mullins.
"He ran a great race in the Belmont Cup on his last run," said Mullins, who saddled
"We were delighted, hopefully he can build on that.
"He drops down in trip a little but I don't think that should bother him too much, in fact it may be a bit better for him.
"He needs to handle the stalls better than he did at Belmont, and he does give some weight."
"I'm looking forward to running him."
Although the Irish St Leger remains the principal target, he will be aimed at the Champion Hurdle at Cheltenham where he finished eighth in 2017.
"This is a good test for him, and we're taking it one step at a time."
"Hopefully he can run well today, and we can go forward from there."
