BOULDER, Colo. -- Former "Family Ties" actor Brian Bonsall has been sentenced to two years probation after pleading guilty to charges connected to a fight with a friend last year in Colorado.

The 28-year-old actor entered his plea Thursday in Boulder to felony menacing and third-degree assault.

Bonsall also pleaded guilty to violating terms of 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, Andy Keaton, on "Family Ties," starring Michael J. Fox.
