Costa Rising, who gained notoriety outside of his home state of Louisiana back in 2007 when he put up two of that year's best Beyer Speed Figures, has been retired, his trainer, Glenn Delahoussaye, said on Wednesday.
Costa Rising has a torn ligament that would require an extended layoff, so the decision was made to retire him, said Delahoussaye.
A 6-year-old son of Royal Strand owned by Charles Castille, Costa Rising will stand at stud in Louisiana.
