On the heels of meetings with the new National Association of Two-Year-Old Consignors, Fasig-Tipton Co. announced Tuesday it will implement random drug testing after workouts at under-tack shows at its 2-year-olds in training sale at Calder.Two under-tack shows will be held, one on Feb. 18, and the other on Feb. 25. The sale is scheduled for Feb. 27. Fasig-Tipton has hired Dr. Thomas Tobin, a professor of veterinary science and toxicology at the University of Kentucky's Gluck Equine Research Center, as an advisor.An independent agency will collect urine samples as horses leave the track. Consignors won't know which horses will be tested, but will be told after the horses breeze which ones have been selected by a pre-determined draw. Urine samples will be tested by Ohio State University.
