The actor who played Screech in the 1990s TV show "Saved by the Bell" has pleaded not guilty to charges resulting from a bar fight in southeastern Wisconsin.

Dustin Diamond and his fiancée, Amanda Schutz (SHUTS), appeared in Ozaukee County Circuit Court Thursday morning on charges stemming from the Christmas Day scuffle at a Port Washington bar.

Diamond is accused of stabbing a man after Schutz became involved in an altercation. The stabbed man told police he had shoved Diamond forcefully and didn't realize he had been cut until later.

The 38-year-old Diamond pleaded not guilty to second-degree reckless endangering safety, a felony, and two misdemeanors. Schutz entered the same plea to misdemeanor disorderly conduct.

Diamond has been free on bond. The judge set a $500 signature bond for Schutz.
