Doctors operated to repair the injury and Hasselhoff spent one night at St. Thomas' Hospital in central London, Katz said. "He's fine," Katz said by phone from New York. "He's out of the hospital and will resume filming tomorrow." Hasselhoff is working on an ad campaign for Pipex, a British internet company, she said.
