The reason the s/p is in the toilet belongs to Rick. Rick should resign ... Yes, I want to change jockeys because I am tired of coming in last in every race with the present one

I think you'll find that Rick took one look at the horse and put it out to pasture to regain strength. In the meantime he went to the yearling sales and picked up a few fillies. Those horses have been seen to do well in recent trials and will be in with a chance of collecting some decent prize money in the not too distant future.

The old horse has been collecting stud fees during recouperation, and once the vet gives the all-clear will no doubt be back in winning form.

At this moment in time, I very humbly suggest, that blaming the jockey for the nobbled horse that he was given is wrong.

Be well
