Between the Kentucky Derby and the Preakness,
Mr. Prospector, Cup Bearer, Ecole Etage, Champagne Charlie, and Step Nicely, none of whom had run in the Derby, were all named as possible entrants. Three horses, Secretariat, Sham, and Our Native, all raced in the Kentucky Derby two weeks prior. The horses officially registered that day were Our Native, Secretariat, and Sham, along with new runners Deadly Dream, Ecole Etage, The Lark Twist, and Torsion. A day later, Deadly Dream's trainer stated that he was unsure about racing his
colt because he felt the horse could not match Secretariat, Sham, or Our Native. In addition, The Lark Twist's owner Larry Boyce scratched his horse from the race because he received word that Our Native registered, dropping the total number of horses competing to six. In the days between the Derby and the Preakness, groom
Eddie Sweat noted that it was strange not having any rumors circulating about Secretariat's health. Aside from Sham and Secretariat, Our Native was selected by Joe Nichols, a writer for
The New York Times, as an outside contender for victory. In pre-race interviews, Deadly Dream's trainer
Bud Delp believed he could challenge for third place as he had no "illusions about beating Secretariat and Sham." Of the remaining contenders, Deadly Dream had won the fourth race of his three-year-old campaign at
Penn National, previously winning the Allegheny Stakes and the Militia Handicap. In total, he won seven races out of the 25 he had started. Ecole Etage had won two races in the 1973 season, prior to the Preakness, the General George Stakes and the Preakness Prep. Torsion entered the race with a most recent finish of fifth place in the Preakness Prep and two wins in twelve career starts, one as a two-year-old and one as a three-year-old. ==Event details==
