In the seventh race at Northfield tonight, No. 3--a 1/9 shot--was leading but several lengths going around the final turn. The number cloth was coming off and finally did fly off. It didn't affect the second and third place horses, but it did cause one trailer to take several bad steps as the cloth flew underneath him. What would have happened if the cloth had flown into the face of a horse that had a legitimate shot of winning or caused a horse to go offstride? Could the horse been disqualified?
