Veteran jockey Noel Fehily will mount Might Bite in the Betfair Chase at Haydock on Saturday, if regular rider Nico de Boinville fails to recover from a thumb injury in time.
De Boinville has been aboard Might Bite for most of the leading chaser's career, but was injured at Chepstow at the end of last month, and has been on the sidelines since then.
He will see a specialist on Wednesday, but Champion Trainer Nicky Henderson, who trains last year's King George winner will turn to Fehily; who is available, if De Boinville is unable to take the ride.
(Credit: Racing Post) Henderson said: "Noel came and schooled Might Bite on our new carpet schooling ground this morning and was very pleased.
"I've never seen him jump so well and, barring mishap, the intention is very much to run."
Might Bite will surely get his ideal conditions, and as a result, is generally an even-money shot to land the Betfair Chase - the opening leg of the Jump's Triple Crown.
Meanwhile, the Colin Tizzard-trained Native River - who denied Might Bite in an epic battle in the Gold Cup back in March, is next best round about the 3/1 mark, with stable companion Thistlecrack, at 9/1.
Fehily, who won a Champion Hurdle for Henderson on Buveur D'Air in 2017, also stood in for De Boinville during Seven Barrows stable star Altior's novice chase campaign.
