Kingmambo, who stands at Lane's End in Kentucky for a $300,000 fee, will miss about three weeks of the breeding season because of arthritis in his neck and possible infection of equine protozoal myeloencephalitis.
Lane's End recently removed Kingmambo, a 15-year-old Mr. Prospector horse, from its lineup after he injured a leg while dismounting a mare, but in a release issued Wednesday the farm said the stallions "is now fully recovered from that incident."
According to the farm, radiographs and a bone scan have shown signs of arthritis at the base of Kingmambo's neck.
