Blinkers

A hood worn on a horse’s head to limit side vision, which can improve concentration. Blinkers are added or removed to relax a horse or give it more focus.

Also Eligible

A horse that is entered but does not draw into the body of the field due to too many entries, and thus is not permitted to start unless there are enough scratches to shrink the field size.
