Racing:Teofilo will join Darley's stallion roster for 2008 and stand at Kildangan Stud in County Kildare, Ireland.
Last year's champion two-year-old, who is to remain the property of Jackie and Jim Bolger, capped an unbeaten five-race season with a memorable victory in the Darley Dewhurst Stakes.
After missing intended engagements earlier this year due to injury, Bolger elected to retire Teofilo last week following an unsatisfactory scan.
"I would expect that Teofilo's stud career will prove to be as illustrious as his racing career and hopeful that one day he will become a champion sire," said Bolger.
"I am a great admirer of Darley's professionalism and the way that they treat their clients; with their support I am extremely confident that Teofilo will be given every opportunity to excel in his stud career, he added.
