PORT WASHINGTON, Wis. (AP) — The actor who portrayed Screech on the 1990s TV show "Saved by the Bell" is headed to trial in southeastern Wisconsin where he's accused of stabbing a man during a confrontation at a bar.

Dustin Diamond is expected in Ozaukee (oh-ZAH'-kee) County Circuit Court Wednesday for the start of his trial on a felony charge of second-degree recklessly endangering safety and two misdemeanors — disorderly conduct and carrying a concealed weapon.

Prosecutors say the 38-year-old Diamond stabbed a man with a pocket knife during an argument at The Grand Avenue Saloon in Port Washington on Christmas Day. Diamond's defense attorney told a judge earlier that of the half-dozen people at the bar who were interviewed by police, no one saw Diamond stab the man, who was not seriously hurt.
