Dolphins wide receiver Brandon Marshall has spoken to prosecutors regarding an April incident in which he was stabbed by his wife. Marshall, who came in under power of a subpoena and spoke with attorneys June 20, hadn't discussed the stabbing with authorities since April 22, when he told police he had fallen on a broken glass vase. His wife, Michi Nogami-Marshall, told Broward County Sheriff's officers she had stabbed him in self-defense. She was arrested on a charge of aggravated battery with a deadly weapon.
