Dennis Weathersby's condition remained serious on Thursday at University Hospital. The 23-year-old Bengals cornerback suffered a head injury Monday night during a one-car auto accident in Springdale. A spokesperson at the hospital reported no change in Weathersby's condition at 4 p.m. Thursday. After appearing in just four games last NFL season, primarily on special teams, he was expected to challenge for regular playing time on defense in 2004.
