Bengals guard Eric Steinbach pleaded not guilty Tuesday to a charge of boating under the influence on the Ohio River, the fifth Cincinnati player in three months accused of breaking the law. A Kentucky Department of Fish and Wildlife Resources officer stopped Steinbach within sight of Paul Brown Stadium, on the Cincinnati side of the river, because he was violating an idle-only zone Saturday night, agency spokesman Mark Marraccini said. He failed a series of field sobriety tests, Marraccini said.
