The 23-year-old was held about seven hours at the Kenton County jail before being released on his own recognizance. Court records show he entered a plea and was ordered to return this month for a hearing.
The Bengals' 2009 second-round draft choice from USC started the first 15 games of his rookie season before breaking his left ankle.
