Windsor Castle, purchased by a Dogwood Stable partnership after winning the grade II Remsen Stakes last year, has been dealt a setback that will cause him to miss the Feb. 17 Fountain of Youth Stakes. Dogwood president Cot Campbell said Windsor Castle developed a fever several days after a Jan. 6 workout. "It's nothing serious and he's normal now, but it's thrown a monkey wrench into (trainer) Frank Alexander's schedule for him," Campbell said.Once the colt resumes his regular training schedule, Campbell said and Alexander will "discuss what Plan B should be. We have the classics in mind for him, of course, and we should have plenty of time to regroup and stay the course. Hopefully, the Florida Derby will be a vital part of that program."Alexander, who previously owned Windsor Castle, retained an interest in the colt with Dogwood and continues to train him.Campbell also said Dogwood's Trippi, the winner of seven of 10 starts last year, will make his 2001 debut in the Gulfstream Park Breeders' Cup Sprint Championship.
