The sportswoman stumbled out onto the street, where she managed to flag down a passing motorist who took her to an Orange County medical centre to seek treatment.
She spoke to police and identified trainer James Martin as the attacker and cops are now on the hunt for the 66 year old.
Martin, who held the World Boxing Council Women’s Jr. Welterweight world championship title in the early 1990s, is widely regarded as one of the most successful and prominent female boxers of all time.
Her one-time promoter Don King has sent his best wishes to the 42 year old as she recovers from her injuries.
He tells TMZ.com, “I am shocked and saddened to see this happen to Christie. I send my prayers and well wishes.”
