Following a headbutt attack Kiefer Sutherland unleashed on designer Jack McCollough earlier this week at SoHo's Submercer, it seems the actor will be paying his dues like a regular 'ol civilian. TMZ reports that he'll be charged with misdemeanor assault, an attack the designer says was unprovoked though allegedly happened after he pushed Brooke Shields (possibly just trying to sidle by her at the crowded bar). The altercation is said to have left McCollough with a tiny gash on his nose, though his reps are making it sound more serious by saying: "He was the victim of a vicious, violent, unprovoked assault." Later today Kiefer, currently on probation for a DUI, will show up at the First Precinct station house downtown and get a desk appearance ticket and his arraignment date set.
