LOUISVILLE, Ky. (AP) – I Want Revenge appeared to be OK on Sunday morning, a day after being scratched from the Kentucky Derby with an ankle injury.

Veterinarian Foster Northrop said he planned to do another scan of the 3-year-old’s left front ankle, but said the joint responded well after the colt jogged on the asphalt outside Barn 24 at Churchill Downs on Sunday.

“I don’t think it was anything career-ending,” Northrop said. “I think it was a minor soft tissue injury that hopefully with a little time, he’ll come back.”

Northrop estimated recovery could take anywhere from 60 days to six months depending on the extent of the injury, but said additional tests will probably be necessary before setting any kind of timetable.

I Want Revenge will likely be sent to Larry Bramlage at Rood and Riddle Equine Hospital in Lexington for further examination. Bramlage, the on-call veterinarian at Churchill Downs, also examined the colt.

early Saturday morning.

“The area that Larry (Bramlage) and I are both concerned (about) is a very serious area,” Northrop said. “It’s the majority of the support and when we usually see a catastrophic injury, that’s normally what we see go which is why we were so alarmed yesterday morning.”

The Wood Memorial winner became the first morning line favorite to scratch the day of the Derby in at least 60 years after trainer Jeff Mullins discovered a hot spot on the ankle just hours before the race.

Owner David Lanzman opted to pull the horse from the Derby rather than risk aggravating the injury.

Mine That Bird, a 50-1 longshot, pulled off the second-biggest upset in Derby history when he beat Pioneerof the Nile by 6 lengths.
