Super Saver, winner of this year's Kentucky Derby Presented by Yum! Brands, has been temporarily sidelined from racing due to condylar bruising.

"After a couple of uncharacteristic post-Derby efforts, we had Super Saver evaluated by Dr. Larry Bramlage at Rood and Riddle," said Elliott Walden, vice president and racing manager for WinStar farm, which bred and owns the bay colt.

"A bone scan was performed on Super Saver which revealed marked activity in all four cannon bones," said Bramlage in a statement. "The left front fetlock has the most radiographic change with a major bruise on the cannon bone. Once these are resolved, the horse should return to his previous form."

Todd Pletcher, who won his first Kentucky Derby with Super Saver, responded to Bramlage's report in a release saying: "This explains a lot to me–I couldn't understand those last few efforts where Super Saver didn't extend and lay it out there like he had in every other race he ran through the Kentucky Derby victory. He has always been very gutsy and determined in his races, even when he set fast fractions, so this answers a lot of head scratching. When he's right, he's the ultimate racehorse
