Multiple Group One winner Epaulette's racing career is over, with Darley announcing the sprinter will retire for stallion duties.
The four-year-old will join Darley's European stallion roster in Ireland before returning to Australia for the 2014 breeding season.
Epaulette raced just 14 times in total but banked more than $1.7 million in prizemoney, with Group One victories in the 2012 Golden Rose and 2013 Doomben 10,000.
He also finished a second to Black Caviar in this year's Group One TJ Smith Stakes at Randwick - the champion Australian mare's final race.
"Epaulette was a brilliant racehorse and he boldly competed against Pierro, All Too Hard and Black Caviar in an epic era," Darley's Alastair Pulford said.
The announcement came on Wednesday, the same day his trainer Peter Snowden publicly voiced his intention to quit as head trainer of Darley Australia's racing stable.
