Track officials at Ruidoso Downs say they are sticking with standards that will ensure integrity during this summer's racing season.
That means no trainers who have been suspended by the American Quarter Horse Association, The Jockey Club or any racing jurisdiction will be allowed to compete at the southern New Mexico track.
Track officials included a list of 17 trainers with Wednesday's announcement.
The track acknowledged that the trainers have certain appeal rights within their racing jurisdictions and Ruidoso Downs will continue to monitor their status.
The season starts May 24, but the track's biggest weekend will be in September. That's when the $2.8 million All American Derby gets under way. It represents the largest purse for the season and in the history of quarter horse racing.
