The five-year-old mare ran a solid race to finish third at Wolverhampton earlier this month, and trainer Arbuthnot believes she would have been even closer but for meeting with interference.
"She ran a great race last time because she met with trouble in running. I still think she would have won if she hadn't had a bump," he said.
"She's a very game mare. She beat Spectait at Sandown last season in very soft ground, but then she slightly went off the boil and that was her first race back, so we were very pleased.
"I think she has a pretty fair chance as the ground will be in her favour and then you just need the luck of the draw."
Zero Tolerance tops the 63 horses left in at the five-day confirmation stage.
David Barron's seven-year-old will have to defy top weight if he is to add to his eight career wins after both Dunelight and Kalderon were taken out.
Dermot Weld's Bawaader, who ran disappointingly in the Irish Lincolnshire on Sunday, will also miss the race.
