Churchill Downs officials received word Sunday that an injury will prevent Outofthebox from competing in Kentucky Derby 127 on May 5. The track immedicatley suspended wagering on the colt in Pool 3 of the Kentucky Derby Future Wager.According to an announcement from the track, Outofthebox suffered a foot injury in a fifth-place finish in Saturday's Flamingo Stakes (gr. III) at Hialeah Park. Steve Flint, assistant to his father, trainer Bernie Flint, told Churchill officials by telephone Sunday that the injury to the colt's right hind leg will keep him on the sidelines for six weeks-to-two months and he has no chance to make the Derby."He clipped heels on the first and pulled a pretty big chunk out of his quarter," Flint said. "When he took his shoe off, it pulled the whole inside wall of his foot off with it. It went pretty good into the foot, so we're going to have to rebuild his foot."Outofthebox has won or placed in seven of nine career starts and had finished second in four stakes, including the Florida Derby.According to the format for the Future Wager, there are no scratches, but wagering can be suspended on a horse when it is determined that an injury or ailment that will prevent the horse from competing in the Kentucky Derby. There are no refunds in the Kentucky Derby Future Wager and the money previously wagered on Outofthebox in Pool 3 will remain in the pool. Wagering on the horse, listed as number 17 in the pool of 24 wagering interests, was suspended about 45 minutes into Sunday's final session of betting on Pool 3.
