After what appeared to be a good workout in preparation for the Santa Anita Derby next month, Kentucky Derby betting favorite Life Is Good suffered a setback and was taken off the Triple Crown trail, the colt’s lead owner said Saturday.

“Out for few months,” WinStar Farm president and CEO Elliott Walden said in a text to Horse Racing Nation. “Off left hind. Going to see Dr. (Larry) Bramlage this week.”

After first hesitating to rule Life Is Good out of the Derby, trainer Bob Baffert confirmed it later Saturday in an off-air conversation with Randy Moss of NBC Sports.

A son of champion sire Into Mischief, Life Is Good had won all three of his races thus far including both the G2 San Felipe Stakes and G3 Sham Stakes.
