Racing: Black Jack Ketchum will not make his handicap bow at Haydock on Saturday after an unsatisfactory blood test.
Jonjo O'Neill's unbeaten seven-year-old was set to take his chance in the Betfair Handicap Hurdle, in which he would have had to carry 11st 12lb.
The ante-post favourite for the Ladbrokes World Hurdle will instead be primed for the Ballymore Properties Long Distance Hurdle at Newbury on November 25.
O'Neill told the Racing Post: "Black Jack Ketchum will not run at Haydock on Saturday as unfortunately, his blood has not quite tested right.
"Hopefully, he will be okay to run at Newbury the following week."
