Ivan Grozny is the sole Irish-trained contender left in the Stobart Rail Northumberland Plate at Newcastle.
Owned by Andrea and Graham Wylie, the Willie Mullins-trained dual-purpose performer was last seen in the Punchestown Champion Hurdle in April when he was sixth behind stable companion Wicklow Brave.
Clever Cookie is likely to attempt to defy top-weight in Saturday's two-mile feature handicap on the all-weather.
The nine-year-old was a disappointing ninth of 10 runners behind Dal Harraild in a two-mile Listed race at York after he uncharacteristically led from the start until about three furlongs from home.
That under-par effort came eight days after he was fourth over the course and distance in the Group 2 Yorkshire Cup, which he had won 12 months earlier.
"He's fine. I don't have many other options so he might run," said trainer Peter Niven.
"He could well run. You kind of expect him to be carrying top weight. A lot of them ran at Ascot so they won't be running."
Second in the weights is James Fanshawe's Higher Power, who was second to Ascot Gold Cup winner Big Orange in the Henry II Stakes at Sandown on his latest start.
Seamour is on course to try to make it third-time lucky in the race. Brian Ellison's smart stayer is among 59 horses left in the race and one of the lucky ones guaranteed a place in the maximum 20-strong line-up.
He has gone off favourite for the last two years, having finished runner-up last year and sixth in 2015, and was third behind Dal Harraild at York. He is currently second favourite behind the Sir Mark Prescott-trained Flymetothestars.
