Marshall's attorney, Harvey A. Steinberg, said the receiver has yet to speak with the Broward State Attorney's office because he disagrees with the no-contact order placed on his wife, Michi Nogami-Marshall, at a bond hearing following the April 22 incident. Marshall and his wife haven't seen each other since.
Nogami-Marshall was charged with aggravated battery with a deadly weapon, and an arrest report said she told officers she was defending herself in the confrontation.
"(Marshall) has never felt threatened by his wife, and misses her," Steinberg said. "When (they) drop the no-contact order, he'll be more than willing to sit down and discuss this matter, bringing some clarity to this unfortunate misunderstanding."
Marshall's failure to cooperate could force authorities to drop the charges because of lack of evidence, the Sun Sentinel noted.
Ron Ishoy, a spokesman for the Broward State Attorney's office, released a statement saying the matter is being pursued, but that "despite numerous efforts, we so far have been unable to get Mr. Marshall to agree to voluntarily speak to our office about the incident."
According to the Sun Sentinel, Marshall has fully recovered from his injury and resumed training two weeks ago.
