This is a direct quote from the article link above...

Jones, who owned and raced Half Ours, a son of Unbridled's Song in partnership with Barry Schwartz, bought out his partner to take total control of the gray or roan 3-year-old colt. Half Ours will remain in training with Todd Pletcher.

Racing for Jones and Schwartz, Half Ours, who has two wins from two career starts, including a win in last year's Three Chimneys Juvenile Stakes, suffered a fracture in his right hind ankle which required pins to be inserted. Jones said the colt has begun working again.
