Horse dies following chuckwagon race at Calgary Stampede

Doug Irvine slaps the reins to win Heat 4 of the Rangeland Derby chuckwagon races at the Calgary Stampede in Calgary, Alberta, on July 12, 2013



CALGARY -- The Calgary Stampede said an autopsy will be conducted on a horse that died after a race Friday.

Hughey, a 12-year-old thoroughbred, collapsed following heat No. 4 of the Rangeland Derby, when the outrider and horse were returning to the infield. A veterinarian on scene determined that the horse had died immediately.

The horse was not involved in a collision or infraction during the heat, and there is no obvious sign of injury.

It had also been cleared to compete prior to the race as part of the Calgary Stampede's Fitness to Compete program.

The horse belonged to Doug Irvine, who has driven at the Calgary Stampede 10 times, and was an outrider for two Rangeland Derby champions.

The horse will undergo a post-mortem to determine the cause of death, which the Calgary Stampede said it will release when the information becomes available.

Earlier this week, a steer died after injuries sustained during the rodeo.
