Bad Blow Could Mean Jail for "Family Ties" Kid

Brian Bonsall, who played Andy Keaton on "Family Ties," may now be facing jail time after violating the terms of his probation.

B.B. pleaded guilty last year to third-degree assault after tossing his girlfriend around -- and has now allegedly violated the terms of his two-year probation by failing to pay for domestic-violence classes, submitting a positive breath test, and failing to show at other scheduled breathalyzer check-ups -- this according to Boulder's Daily Camera.

The 26-year-old is due in court on Wednesday in Colorado and his probation officer has recommended a 60-day term of work release -- allowing him to work during the day and go back to the pokey at night.
