RENO, Nev. — Pittsburgh Steelers quarterback Ben Roethlisberger has been named as a defendant in a lawsuit filed by a woman in Nevada.

According to online court records, a defamation lawsuit was filed in Washoe County on Friday. Andrea McNulty is listed as the plaintiff.

Details of the suit were not available late Monday night. Roethlisberger was one of nine defendants listed in the online court docket report.

Roethlisberger’s attorney released a statement to several media outlets Monday night saying the two-time Super Bowl winner was accused of sexual assault in the lawsuit by McNulty. Atlanta-based attorney David Cornwell denied Roethlisberger sexually assaulted McNulty.

‘‘This weekend Andrea McNulty served Ben Roethlisberger with a civil complaint accusing him of sexually assaulting her in July 2008. Ben has never sexually assaulted anyone; especially Andrea McNulty. The timing of the lawsuit and the absence of a criminal complaint and a criminal investigation are the most compelling evidence of the absence of any criminal conduct. If an investigation is commenced, Ben will cooperate fully and Ben will be fully exonerated,’’ Cornwell said.
