The Preakness is out for trainer Todd Pletcher.
Pletcher said Tuesday he will not enter any of the four horses he was considering for Saturday's Preakness at Pimlico Race Course.
Materiality is expected to run next in the Belmont Stakes on June 6 after finishing sixth in the Kentucky Derby despite a troubled tri.
Pletcher's other Preakness possibilities were Derby 10th-place finisher Carpe Diem; Competitive Edge; and Stanford.
With the decision, the Preakness could be left with seven starters, the smallest field since 1986. Derby winner American Pharoah, and second- and third-place finishers Firing Line and Dortmund top the lineup. Others include Danzig Moon, Divining Rod, Bodhisattva and Tale of Verve.
Entries are taken Wednesday.
