Sizing Europe will miss the rearranged William Hill King George VI Chase at Kempton on Saturday.
Connections of the 2010 Arkle Trophy winner have decided against sending the nine-year-old over to England for the second time in three weeks after making a wasted journey for the abandoned Christmas meeting.
Instead, trainer Henry de Bromhead will attempt to give Sizing Europe a run before Cheltenham nearer home.
"After careful consideration we've decided to bypass the rearranged King George this Saturday with Sizing Europe," he told his website, www.henrydebromheadracing.com.
"He's in great form at home so what we'll do now is sit down and look at our options here over the next three to four weeks with a view to a run prior to the Festival in March."
Kauto Star will be seeking a record fifth successive victory in the race and the the three-week delay and the forecast softer ground conditions will play to his strengths, according to Paul Nicholls.
The Ditcheat handler told At The Races: "He had a nice little break for a week after the day it was due to be run. He still cantered every day, we have just picked him up quietly and he's in really good form. It doesn't seem to have affected him at all.
"He worked great on Saturday morning and we are very happy with him. He was in good order when he won at Down Royal and he's improved a lot for that run.
"It is a totally different race to what it would have been on Boxing Day. It would have been really good ground then, on Saturday if the forecast is right it looks like being really soft.
"That will be more of an advantage to him than it was on Boxing Day because a lot of horses would have have been a bigger threat on good ground whereas on soft ground it will go against some of them."
