California Highway Patrol officials say Holli Griggs of Huntington Beach, Calif., was driving in Newport Beach, Calif., last month when a car driven by Jackson clipped her, crumpling her driver's side door and a rear corner of the vehicle.

The Orange County Register reported Tuesday that Griggs' attorney says the 38-year-old woman, who was 16 weeks pregnant, miscarried as a result of the accident.

Jackson, until recently an Ultimate Fighting Championship titleholder, declined to comment, the Register said. Jackson, 30, of Irvine, Calif., was arrested on suspicion of hit-and-run driving, felony evading and reckless driving but has not yet been charged, the newspaper said.

Police say Jackson went on a tear through Newport Beach July 15, allegedly hitting three motorists and causing pedestrians to flee when plowing onto the sidewalk.
