Unbeaten Breeders' Cup Juvenile Fillies (G1) winner AWESOME FEATHER (Awesome of Course) has a tendon issue that puts in her racing future in jeopardy, Daily Racing Form reports.

Purchased for $2.3 million by Frank Stronach's Adena Springs at Fasig-Tipton Kentucky November sale, Awesome Feather was sent to conditioner Chad Brown in Florida but hasn't been in serious training.

"She's got a bit of a profile in her tendon," the DRF was told by Mike Rogers, who serves as business manager for Adena Springs as well as director of racing operations for Stronach's MI Developments. "Right now we are not overly concerned but being very cautious because tendon injuries can be career ending."

Awesome Feather, who is expected to be named champion two-year-old filly at Monday night's Eclipse Award ceremonies, was campaigned by Jacks or Better Farms and trainer Stanley Gold last year.

"We don't really know if this was a pre-existing condition or not," Rogers said. "But we've been monitoring it ever since her arrival at Palm Meadows. Frank brought the filly as a broodmare prospect, but hopefully we'll be able to get her back to the racetrack again."
