NASHVILLE, Tenn. (AP) - Arcadius collapsed and died as he was being cooled down after winning the $150,000 Iroquois Steeplechase at Percy Warner Park on Saturday.

The 8-year-old gelding collapsed at a station placed just beyond the finish line of the 3-mile race.

Dr. Marty McInturff, one of five official veterinarians on the course, said Arcadius succumbed from "a heart attack" and a possible aneurysm. The results of a necropsy examination are expected Monday at the earliest.
