Dustin Diamond, the actor who played Samuel "Screech" Powers on the '90s sitcom "Saved by the Bell," received a four-month jail sentence on Thursday for stabbing a man during a bar fight last Christmas.

Wisconsin Judge Paul Malloy handed Diamond the light sentence along with 15 months of probation and ordered him to report to jail on Sunday, reports The Associated Press.

Diamond was convicted of two misdemeanor counts following a three-day jury trial earlier this month. The jury found him guilty of carrying a concealed weapon and disorderly conduct, but cleared him of a felony charge of recklessly endangering public safety.

The incident occurred in December 2014 when the 38-year-old former child star was taken into custody by police in Ozaukee County for allegedly stabbing a man with a switchblade during a fight at the Grand Avenue Saloon in Port Washington on Christmas night.

According to The Associated Press, the jury issued a verdict just hours after the former child star testified that he never intended to stab anyone in the December fight.

In a criminal complaint, Diamond and his fiancée Amanda Schutz, 27, got into a physical altercation with two men and a woman. Court documents show the victim suffered from a non-life-threatening, 1/2-inch wound under his armpit and heavy bleeding. However, Diamond told police he accidentally stabbed one of the men while trying to defend his fiancée. Schulz is still facing a misdemeanor charge for disorderly conduct.

According to court documents, Diamond said, "There was a group of intoxicated people being rude and insulting" at the bar that night. He also claimed he intervened after his girlfriend got into an altercation with another woman and was bleeding. Diamond said he unintentionally stabbed the man while "chaos broke out and people were grabbing at him."

The stabbing victim, a 25-year-old man identified as Casey Smet, also testified during the trial, saying he did not realize that he had been stabbed until after he left the bar and began speaking with police.
