Cheveley Park not so Lucky for Kristale Lucky Kristale is rated as "very doubtful" for Saturday's Connolly's Red Mills Cheveley Park Stakes at Newmarket. Trainer George Margarson is concerned about the health of his dual Group Two winner after the filly returned an unsatisfactory scope and blood test on Monday. He said: "She worked on Monday morning and then we scoped and blood tested her afterwards and the results were not what I would have liked. "She'd been a bit quiet which is unlike her as she's usually a bit of a fizzy filly. "If she'd been quiet for a few days and returned those tests I might have thought she was just getting over something, but I think she might be just starting to come down with it. There's a lot of it going around in the town. "I would say, in my mind, she's very doubtful for Newmarket at the moment. "We will probably give her a little breeze on Wednesday morning, do the tests again and take a decision from there." Lucky Kristale had been in line for a potential rematch with Rizeena, who she beat in the Duchess Of Cambridge Stakes at Newmarket back in July.
