Jack McCollough, the designer who was head butted by Kiefer Sutherland released a statement about the incident.  Or, rather, his rep did:

“Anyone who knows Jack McCollough knows that he would not hurt a fly. All we can say at this point is that he was the victim of a vicious, violent, unprovoked assault and that the matter is in the hands of the authorities.” 

TMZ.com is reporting that Kiefer will be charged with misdemeanor assault for the incident.  Since the star is already on probation for a DUI charge, I wonder if jail time is once again in his future?
