The Dolphins' Chad Johnson was arrested tonight on domestic violence charges, according to the Sun-Sentinel.
Johnson and his new wife Evelyn Lozada were major players in last week's premiere episode of HBO's Hard Knocks. (You can view some of those highlights here.) BlackSportsOnline claims Johnson allegedly head-butted his wife while "play-fighting."
