Normandy Invasion, who finished fourth in Saturday's Kentucky Derby, and Vyjack, who was 18th, were added Monday to the list of potential candidates for the Preakness Stakes.
Orb, who won the Derby over a sloppy track, will run in the second jewel of the Triple Crown.
"Originally, I threw the Preakness out," Normandy Invasion's trainer, Chad Brown, said Monday, "but he's come out of the race so well that I'm at least going to remain neutral on the topic until I can see the horse go back to the track and get a gauge on his energy level and his soundness."
Brown said that a decision on the May 18 Preakness likely would be made by this weekend.
Departing, bred and owned by Claiborne Farm and Adele Dilschneider, was a Derby candidate but was taken off the trail when he finished third in the Louisiana Derby behind Revolutionary and Mylute.
Departing was sent to Hawthorne Park on April 20 to run in the Illinois Derby, and he cruised to a 31/4-length victory from an outside post. With four wins in five career starts, the War Front gelding heads the list of new contenders headed to Pimlico for the 138th Preakness.
Derby starters confirmed for the Preakness are Goldencents (17th) and the D. Wayne Lukas-trained duo of Oxbow (6th) and Will Take Charge (8th).
