Lake Delton police chief Thomas Dorner said Wednesday that Underwood appeared in Sauk County Circuit Court to enter the plea to a charge of prostitution-nonmarital sexual intercourse. Dorner declined further comment.
Underwood, a 24-year-old cornerback who mainly contributed on special teams, was accused by two women of sexual assault June 5 after he had been in Wisconsin Dells for a charity event. His lawyer didn't immediately return a call seeking comment.
Underwood was ordered to pay a $379 fine. His record can be expunged in a year.
The Milwaukee Journal Sentinel first reported the resolution of the case.
