NEW YORK — William T. Young's Flanders, undefeated in three starts and a leading contender for 2-year-old filly divisional honors, produced a urine sample that tested positive for Isoxurpine, a vaso-dilator used to improve circulation in the foot, after her victory in Belmont Park's Grade I Matron Stakes on Sept. 17. The drug may be used, but only up to 36 hours before a race.
Barring a successful appeal, the filly will be disqualified from the Matron's winner's share of $64,740.
In addition, trainer D. Wayne Lukas faces a 45-day suspension that would become 60 days if his appeal is thrown out. Lukas is pinning his hopes for a successful appeal on the outcome of a test of a sample of the urine that was sent to another lab.
