The action-drama is set to start production on its eighth season at the end of the month, but star Kiefer Sutherland is caught up in an action-drama of his own that threatens to interfere with production.

Sutherland allegedly noggin-knocked clothing designer Jack McCollough at a New York club on Monday night. No charges have been filed, though The New York Daily News and The New York Post are reporting that prosecutors plan to charge the actor with minor assault and that Sutherland intends to surrender as early as tomorrow. Fox, 24 producer 20th TV and Sutherland's publicist had no comment.
