Dolphins receiver Chad Johnson was arrested Saturday night for misdemeanor domestic battery, according to the Davie (Fla.) Police Department. Johnson is in police custody, and will have to see a judge before he can be released. The argument started in the couple's car. As they pulled into their driveway, Johnson's wife, reality TV star Evelyn Lozada, claims Johnson leaned over and headbutted her, while Johnson claims Lozada leaned forward and they bumped heads. Lozada has a laceration on her forehead, and was treated on the scene and transported to the hospital.
