The four-year-old speedster had his hind leg trapped on a ledge in his stall when the gates opened at the start of the Diamond Jubilee Stakes and trailed home at the rear of the field.
As a result, he was forced to miss the July Cup at Newmarket, which he won in 2017 ahead of his Sprint Cup success.
“He was bruised after Ascot, more than we realised at the time. But he is back now, and I couldn’t be happier with him,” Cox told www.godolphin.com.
“He has a high level of form at Haydock. He loves the place. He broke the course record there when he won the Group Two Sandy Lane Stakes, and he won last year’s Sprint Cup (on heavy ground) as well.
“Because he was forced to miss the July Cup, he comes to Saturday’s race a fresh horse. He’s back in a good frame of mind, and I’m very happy with him.”
