The Pro Bowler was arrested at about 10:10 p.m. Monday after officers believed a domestic violence incident happened, the department said.
Green was taken to the Brown County jail but he posted bond and was released at about 11:50 p.m.
Packers general manager Ted Thompson released a statement that said the organization was trying to get more information on the situation.
"We obviously care about Ahman and the entire Green family, and we will continue to support them through this time," he said.
The organization wouldn't make further comments because it was a legal matter, he said.
Green is married with two daughters and a stepson. He was arrested at his home in Lincoln, Neb., in March of 2002 for a disturbance in which he was accused of abusing his former wife.
Green has been with the Packers since 2000 and was selected to the Pro Bowl the last four years.
He is second on the team's all-time rushing list after starting his career in Seattle. He played college football at the University of Nebraska.
