Roethlisberger has not been charged. Police say a 20-year-old college student reported the assault after an encounter with Roethlisberger at a nightclub in central Georgia.
Police in Milledgeville plan a news conference Monday afternoon on the case.
Meanwhile, the assistant for attorney Ed Garland confirms that he is representing Roethlisberger. Garland previously represented rapper T.I. on a federal weapons charge and Baltimore Ravens linebacker Ray Lewis in a murder case. More serious charges against Lewis were dropped and he pleaded guilty to a misdemeanor obstruction of justice charge.
