Diamond played Screech on the 1990s TV show. He was convicted in June of carrying a concealed weapon and disorderly conduct, both misdemeanors. He was cleared of a felony. He was to start jail during the summer, but a judge put the sentence on hold while Diamond appealed. Diamond withdrew his appeal last month.
Diamond testified he was trying to protect his girlfriend when he pulled out a pocketknife to ward people off and accidentally stabbed a man at the Port Washington bar on Christmas in 2014.
Port Washington is 25 miles north of Milwaukee.
