"She came out of the race with a bad lung infection and she bled some," Dutrow said. "She might have picked something up on the way out there."
Dutrow said Carson Hollow is expected to rejoin the stable after he ships down to Palm Meadows in Florida. After arriving, she'll resume light training.
The 3-year-old daughter of Carson City, who is owned by Stronach and Hemlock Hills Farm, has won five of her seven starts this year. She did not race as a 2-year-old. Although she has captured the grade I Prioress and grade III Floral Park Handicap, she is best remembered for her stirring stretch battle with You in the grade I Test Stakes, in which she was beaten a nose.
