Darvin Ham of the Milwaukee Bucks was arrested on what police said was suspicion of violence against his wife.
The 6-foot-7, 240-pound forward was cited on suspicion of domestic violence-battery, a misdemeanor, at about midnight Monday at a Milwaukee home, Lt. John Andrews said.
Ham paid $500 bail and was released Tuesday, a Milwaukee County jail booking clerk said.
"I am very sorry about the situation and for the anguish and embarrassment this has caused my wife and our entire family, as well as the Bucks organization, my teammates and fans," Ham said in a statement released by the team Tuesday.
Ham called the incident "not representative of my character" and promised to work with his family to rectify the situation.
"My wife means the world to me and I will not let one lapse in judgment overcome my love and commitment to her and to our children," he said.
Milwaukee General Manager Ernie Grunfeld said he is confident Ham will try to resolve the situation.
"This is a very serious matter that shouldn't be taken lightly, and with him it won't be," Grunfeld said. "Darvin and his wife and family know they have the care and support of the entire organization behind them."
The Bucks, who lead the Central Division, play at Minnesota tonight.
