Johnson was arrested for misdemeanor domestic battery in L.A. on February 7, 2000 … just before he began playing football for Oregon State University.
Sources close to the case tell us the victim was his GF at the time … and she told police the football star had slapped her in the face after he accused her of cheating on him.
According to court records, Johnson — 22 years old at the time — pled no contest … and the court found him guilty of domestic battery.
Johnson was sentenced to 45 days in jail, and 3 years probation, but struck a plea deal where he was only ordered to do 30 days of graffiti removal, and 12 months of domestic violence counseling. He was also ordered to stay away from the victim.
The site reports that Chad failed to complete his graffiti removal in a timely manner and was given an additional 15 days clean up duty that he finished when he was with the Bengals.
