A charge of disorderly conduct against Pittsburgh rookie receiver Santonio Holmes was dropped Thursday. Holmes, the team's first-round pick, was among hundreds of people arrested as part of a police crackdown on revelers who annually converge on Miami Beach during the Memorial Day weekend. Prosecutors dismissed the charge against the Steelers' first-round draft pick, but he was ordered to donate $250 to the police officers assistance trust fund. The 22-year-old Holmes had pleaded not guilty to charges that he blocked traffic and refused to obey a police order to move.
