The fight is on: In a news conference on Thursday, Pittsburgh Steelers' Ben Roethlisberger forcefully denied sexually assaulting Andrea McNulty, a 31-year-old Lake Tahoe casino hostess. "I would never, ever force myself on a woman," the Super Bowl-winning quarterback said. "I want to fight to protect my family and my reputation." Last Saturday was the first he'd learned of the allegations, he said, which were detailed in a civil suit filed by McNulty. In it, the Harrah's employee accuses Roethlisberger of raping her in a penthouse suite last July. "I'm not going to discuss my private life or this civil case in the media," he continued. "I'll respond to her outrageous allegations in the appropriate forum."
