Trainer Nick Zito decided to keep The Cliff's Edge's out of the race. The horse's status had been in doubt all week because of an abscess in his right foot.
The Preakness, second leg of horse racing's Triple Crown, will be run at 6:05 p.m. Saturday at the 1 3/16-mile Pimlico Race Course.
The Cliff's Edge had the No. 4 post. Horses drawn to the outside will now move up one spot.
Kentucky Derby winner Smarty Jones, ridden by Stewart Elliott, was the early favorite at 8-5. The undefeated horse will run from No. 6.
Lion Heart and Imperialism, the second- and third-place finishers in Derby, were at 3-1 and 5-1 in the Preakness morning line. Lion Heart is in the No. 1 post position and Imperialism moves up to No. 7
Others in the field are Rock Hard Ten, Eddington, Borrego, Water Cannon, Song of the Sword, Sir Shackleton and Little Matth Man with the longest odds at 50-1.
