A hearing in the case of trainer Cole Norman, who goes to trial April 3 for a manslaughter charge stemming from an car accident a year ago in Hot Springs, Ark., has been pushed back a week to March 10. The hearing concerns a motion by the state of Arkansas to revoke Norman's bond because, since the fatal accident, he was arrested in Louisiana for driving under the influence of prescription drugs. . . . Stall applications for the upcoming Calder Race Course meeting are due in the office of the track's racing secretary, Mike Anifantis, by Wednesday.
