The popular rider Calvin Borel, a three-time winner of the Kentucky Derby, will be sidelined for the remainder of this year with injuries sustained during Saturday's Delta Downs Jackpot.

Borel was aboard Aces N Kings when the 2-year-old colt bolted leaving the final turn. Borel was unseated and then kicked by a trailing horse, breaking his lower jaw and sustaining a deep facial laceration. He underwent surgery Sunday.

"Another update on Boo - Surgery went very well," Borel's wife, Lisa, posted on his Facebook fan page Sunday night. "His jaw is wired shut and the surgeon did use pins and rods to stabilize the lower right jaw bone at the joint. He is sleeping peaceful right now and thank you all again for all of the amazing well wishes, we appreciate it so very much!!"

Aces N Kings, who apparently locked a stifle, was unharmed.
