The civil lawsuit filed by McNulty, a former Lake Tahoe casino host, claiming the NFL star raped her while he was in town for a golf tournament in 2008.
Neither side will say if Andrea McNulty was paid in the settlement.
Ben Roethlisberger
McNulty filed the suit in Washoe District Court in 2009, claiming Roethlisberger lured her into his Harrah's penthouse suite and forced her to have sex.
The suit also named a list of Harrah's employees, claiming they covered up the alleged sexual assault to protect the Pittsburgh Steelers superstar.
McNulty's lawyer, Cal Dunlap, refused to discuss the terms of the case. Roethlisberger's lawyer, David Cornwell, and his agent, also had no comment.
McNulty claimed Roethlisberger asked her to come to his suite to fix his broken television, only to force her onto the bed and rape her, the suit said.
Lawyers for Roethlisberger denied the claims, and the casino denied covering it up. McNulty was accused by some of trying to extort money from him.
The star faced similar allegations in Georgia only one year later when a second Ben Roethlisberger accuser said he sexually assaulted her after a night of drinking.
Authorities investigated the allegations, but no charges were filed.
