HOT SPRINGS, Ark. – Champion 2-Year-Old Filly Take Charge Brandi will miss her planned showdown with Champion 2-Year-Old Male American Pharoah in Saturday’s G2 $750,000 Rebel Stakes at Oaklawn Park, her Hall of Fame trainer D. Wayne Lukas announced Tuesday morning, because of a non-displaced chip in her right knee.

Lukas said the filly, owned by Willis Horton of Marshall, Ark., is expected to miss about 60 days. He discovered the chip Tuesday morning following training Monday. Lukas said Take Charge Brandi was “a little tender” Tuesday morning and at first he thought if might be an issue with a foot.

He then found a little bit of heat in her knee and went over her “top to bottom.” X-Rays were taken and transmitted to Dr. Larry Bramlage at Rood & Riddle in Kentucky.

“We’re going to take a positive approach to this,” Lukas said. “She’s only going to be out 60 days.”

Take Charge Brandi will be taken to Rood & Riddle Wednesday so that Bramlage can determine whether surgery is necessary.
