Brian Bonsall (PICTURE): "Family Ties" Actor Gets Probation Over Fight

BOULDER, Colo. (CBS/AP) Brian Bonsall, the former child actor who played Andy Keaton on the hit show "Family Ties," has been sentenced to two years of probation over a fight with a friend in Colorado last year.

Bonsall pleaded guilty Thursday in Boulder to felony menacing and third-degree assault.

The menacing charge won't appear on his record, if he stays out of trouble for two years.

The 28-year-old also pleaded guilty Thursday to violating terms of his probation stemming from a 2007 assault on his girlfriend and was sentenced to five days in a work-release program and 40 hours of community service. Bonsall had tested positive for marijuana.

His attorney told a judge Bonsall has substance abuse issues.

Bonsall played the youngest son on "Family Ties," starring Michael J. Fox.
