LOUISVILLE, Ky. (WDRB) -- The following is a rough timeline of events for Justify's 2018 Triple Crown run.

It was built using information from The New York Times' expose of a failed drug test and efforts by California horse racing officials to make it go away.

Read the full NYT story here for more information.

April 7, 2018 – Justify wins the Santa Anita Derby, punching his ticket for the Kentucky Derby as the likely favorite. Post-race blood and urine samples are taken for drug testing purposes.

April 10, 2018 – Blood and urine samples from Justify and other horses who raced on April 7 at Santa Anita are shipped to the University of California Davis for testing.

April 18, 2018 – The lab sends notice that Jusify has tested positive for the prohibited substance scopolamine, a performance enhancer at the levels (300 nanograms per milliliter) found in Jusify’s sample.

April 20, 2018 – California Horse Racing Board equine medical director Dr. Rick Arthur emails the board to inform members that Justify’s case will be “handled differently than usual.” He asks for more testing and review of the data.

April 26, 2018 – Justify’s trainer, Bob Baffert, is notified of Justify’s positive drug test after the Santa Anita Derby. He asks for a second test from the sample to be conducted by an independent lab, as California regulations permit.

May 5, 2018 – Over a sloppy, sealed track, Justify stays just off the leader for the first three-quarters of a mile, takes the lead with a half mile to go, and is never truly threatened while beating Good Magic by 2 ½ lengths. He becomes just the second colt to go unraced at 2 before winning the Derby.

May 6, 2018 – Justify is brought out of his barn for reporters and fans, and appears to be walking gingerly on his left hind leg. Baffert says the colt had some scratches above the hoof, likely due to the sloppy track.

May 8, 2018 – A second lab confirms the positive scopolamine test. Rick Baedeker, the executive director of the California Horse Racing Board, informs board members of the positive test and tells them in a memo obtained by The New York Times that, “The C.H.R.B. investigations unit will issue a complaint and a hearing will be scheduled,” but no complaint is issued, nor is any hearing scheduled.
