Perhaps he just took a day off.

The actor who famously chased down Matthew Broderick in "Ferris Bueller's Day Off" as Principal Ed Rooney is in trouble with the law -- for allegedly not updating his information as a sex offender.

Jeffrey Jones, who was busted in 2003 for employing a 14-year-old boy to pose for sexually explicit photos, failed to keep his information up to date with California after his birthday, the Los Angeles county district attorney's office said.

The 63-year-old actor, who most recently starred in episodes of HBO's "Deadwood," was arrested last week and was relased on $20,000 bail.

Jones was similarly charged in 2004 for failing to update his status. He had pled no contest to the original 2003 charge, for which he received five years probation. His name was also placed on the sex offender registry for the rest of his life.

The "Howard the Duck" star is expected to be arraigned on July 14.
