Tampa Bay Derby (G3) winner ODYSSEUS (Malibu Moon) exited his last-place finish in Saturday's Blue Grass S. (G1) with a bone chip, owner Satish Sanan told the Paulick Report Monday morning. The Padua Stables colorbearer, who was ranked 26th on the graded earnings list with $183,750, is thereby out of Kentucky Derby (G1) consideration.

Sent off as the 5-1 third choice in the Blue Grass, Odysseus set the pace along the rail before giving way abruptly after six furlongs. It was a thoroughly uncharacteristic effort from the Tom Albertrani trainee, who had won three straight since finishing second in his career debut.

Although Odysseus was initially reported to be fine after the Blue Grass, he became lame Sunday. The colt was X-rayed and found to have a bone chip in the back of his left knee.

"It's a bit unusual -- it's rare to have a chip in the back of the knee," Sanan told the Blood-Horse. "He must have hyperextended himself in the race."

A gritty, half-length maiden winner at Gulfstream Park in January, Odysseus stamped himself as a potentially high-class colt with a 15-length allowance romp at Tampa Bay the following month. Next time out in the Tampa Bay Derby, he looked beaten turning for home, but rallied strongly to score by a nose.

Odysseus sports a mark of 5-3-1-0 with total career earnings of $223,670.
