Dwyre states in his article -

"At Churchill this year, one horse had to be put down after an accident Thursday and another during a Breeders' Cup race Saturday."

Did I miss something? I know Calvin Derailed jumped off Atta Boy Roy after the wire, but it was later stated that they couldn't find anything wrong with the horse.

Was there some other horse that was injured and put down?

Rough Sailing.

OK, thanks. Coffee not kicked in yet. I wasn't reading it right.
