Horse dies at Belmont Park after sustaining injury during race ahead of next week's Triple Crown finale

A horse died following a race at Belmont Park after sustaining an injury Thursday ahead of next week's Triple Crown finale.

According to the Equibase race chart notes, 6-year-old horse Chaysenbryn suffered a right front leg injury after bumping into Dolce Sera nearing the quarter pole in the third race at Belmont Park.

The Rudy R. Rodriguez-trained Chaysenbryn had to be pulled up by jockey Joel Rosario and was euthanized on the track, according to the New York Gaming Commission.

"Despite the immediate response by attending veterinarians and members of the New York Racing Association's Safety and Integrity Team, the injury was not operable and catastrophic in nature," New York Racing Association Vice President of Communications Patrick McKenna said in a statement to CNN.

Thursday's incident marks the second for Rodriguez this week after three-year-old Midnight Empress had to be vanned off by an equine ambulance following the ninth race on Sunday.

Since January, Rodriguez has had four horses die, three at Aqueduct Racetrack and one at Belmont Park.

Chaysenbryn is the second horse to be euthanized following a race at Belmont Park since last month, after the Mertkan Kantarmaci-trained Reed Kan sustained an injury to the right front leg at the 16th pole while racing May 13.
