A San Diego judge has ruled that the 33-year-old Phillips must stand trial on eight felony charges for two alleged assaults.
He could face up to 25 years in prison if convicted.
A call to his public defender on Thursday was not immediately returned.
Phillips already is serving a 10-year sentence for hitting three teenagers with his car in Los Angeles.
Phillips was once one of the nation's top college football players at Nebraska. The St. Louis Rams released him in 1997 and he went on to play for a number of teams.
