Trainer Kenny McPeek finally found out Monday morning why Repent hasn't been changing leads lately. After examining the son of Louis Quatorze at 11 o'clock, McPeek noticed his left front ankle felt "suspicious." It was then discovered the colt had a chipped bone, which will sideline him for an indefinite period."We had him X-rayed after the Louisiana Derby, just to make sure there was nothing wrong with him, and the X-rays all came up clean," McPeek said. "He seemed to have come out of the Illinois Derby in good shape, but when I felt his ankle (Monday) morning I knew something was wrong. It's nothing serious, but it's in the colt's long-term interests to give him time off. He'll come back 100 percent. These things happen in racing and you have to accept it. We've had a great year, and things can't be rosy all the time. The owner took it bad when I told him, so it wasn't the right time to bring up Take Charge Lady (also owned by Feye and Jerry Bach's Select Stable)."McPeek said Repent's chip was considered a P-1 fracture (dorsal medial first phalanx chip fracture). It's a small sliver off the ridge of the ankle where socket holds the ball of the joint.McPeek had to convince Bach to put up the late Triple Crown nomination fee for Take Charge Lady as a back-up, in case something happened to Repent. Now he may try to convince him to point her for the Derby, something he wanted to do after her resounding victory in the Ashland Stakes.McPeek now must turn his complete attention to Harlan's Holiday, who runs in Saturday's Blue Grass Stakes.Repent had scored victories in the Risen Star and Louisiana Derby this year before finishing a well-beaten second in Saturday's Illinois Derby.
