Roo Art, second in the Preakness Prep last week after encountering serious bumping on the backstretch, is lame in the left hind leg and will not run in Saturday's Preakness, his trainer, Barclay Tagg, said today.

The absence of Roo Art leaves jockey Donald Miller open to accept the mount on I Am The Game, a long shot trained by King Leatherbury.

Chief's Crown, the overnight favorite for the Preakness, worked an easy half-mile early this morning in 49 seconds. The son of Danzig was allowed to coast through the early stages of his trial, then exercise rider Harry Milligan let out a notch and he sped the last eighth in 11 3/5 seconds.

Eternal Prince, the colt expected to give Chief's Crown the most competition, galloped a strong two miles under the scrutiny of trainer John (Butch) Lenzini, who said, "He had a slight pus pocket under his left front shoe that we cut away and, as you can see by the way he's galloping, he's fine. I feel confident he'll run big on Saturday."

Eternal Prince finished next to last in the Derby after getting away slowly under jockey Richard Migliore, who has been replaced by Chris McCarron.

Drawing for post positions for the 110th Preakness will take place Thursday morning.
