ATLANTA — Pittsburgh Steelers quarterback Ben Roethlisberger has hired a high-profile Atlanta defense attorney as police investigate a Georgia woman's claim he sexually assaulted her.

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.
