I’m Johnny Cash, 18 year old stallion, owned and loved by the Holbrook family and ridden by Mike Conley, succumbed to heat following a second workout in the stake class at the Tennessee State Championship horse show.

The stallion appeared fine during the workout, but collapsed to the ground while in the line up.

Attempts to revive him were made unsuccessfully. I’m Johnny Cash was given a final round of applause as he was placed on a gate, covered and carried out of the ring.
