Unfortunately, every state is different. I was recently watching racing from Oaklawn & fortunately, on a race that I didn't have anything on, a part of an entry was a late scratch. At NYRA if that happens the entry is scratched from betting & the horse runs for purse only with consolations on the entry. In Arkansas, if half the entry scratches, you're stuck with the other half. I felt sorry for the bettors who got stuck with a horse that they may not have ever bet on its own.
