Wyck Hill and Nacarat are among 14 remaining entries for the Racing Plus Chase at Kempton on Saturday, in which Katenko is a notable absentee.
Trainer Venetia Williams had mentioned the valuable event after her Gold Cup hope won at Cheltenham, but she instead relies upon Summery Justice.
Wyck Hill beat Katenko at Ascot and David Bridgwater's charge still holds entries in the Gold Cup and the Grand National.
Bridgwater said: "We're thrilled with how he's been and can't wait for Saturday.
"It's a £100,000 handicap so it's going to take some winning. Henderson and Nicholls are bound to have something lined up, but we're honoured to be favourite.
"We've been in discussions with some people about selling him as I own a bit of him as well, but at the minute all there have been are discussions."
Tom George's Nacarat won the race for a second time last year, having firstly struck in 2009. He also also finished second and third in previous renewals.
Paul Nicholls has left in the top-weight What A Friend, Rolling Aces and Join Together, while Nicky Henderson's possibles are Roberto Goldback and Quantitativeeasing.
Hector's Choice, last year's runner-up, could aim to go one better.
Race specialist Philip Hobbs can chose from 2011 winner Quinz and Duke Of Lucca. Opening Batsman, Same Difference and Mister Hyde are also engaged.
