Aidan Coleman has been booked to ride The Rainbow Hunter in the John Smith's Grand National on Saturday week.

The nine-year-old, who is a 66-1 outsider, has been ridden by Jason Maguire and Nick Scholfield on his three outings this term but neither is likely to be available for the Aintree feature.

Trainer Kim Bailey and owners the May We Never Be Found Out Partnership has duly moved to secure Coleman as a replacement.

Partnership member Oli Bell tweeted: "Aidan Coleman has been booked to ride The Rainbow Hunter in this year's Grand National."
