Jockey Paco Lopez apologized Thursday for his actions at Parx Racing on Tuesday, when he struck a horse in the neck with a crop during the gallop out after the fifth race.
Lopez was suspended indefinitely by the Horseracing Integrity and Safety Authority for the incident.
"I take full responsibility for my actions," Lopez said in an X post. "I am aware that our sport is under a lot of scrutiny and I fully apologize to everyone involved in our sport – fans, horsemen, management, racing commissions, HISA and of course, national law. My actions were reactionary, in the heat of the moment, and I am truly sorry."
Lopez said he has decided to take time away from racing, seek counseling "and work on myself."
Video posted on X showed Lopez striking National Law after 2-year-old colt National Law won the maiden special weight race despite drifting out to the outer rail.
HISA CEO Lisa Lazarus said in a statement Thursday, "Today I spoke at length with Paco Lopez’s representatives. They shared Lopez's remorse for his actions and his commitment to undergo counseling to address his recent conduct.
"We also agreed Lopez would make meaningful donations to the Permanently Disabled Jockeys Fund and Thoroughbred aftercare organization Second Call prior to the end of the year and that we would meet after he completes his counseling program to discuss his progress.
