The 43-year-old rap producer entered the plea in Las Vegas Justice Court Tuesday in a deal that dismissed two felony drug charges and one felony coercion charge stemming from the August incident.
Police said officers witnessed the co-founder of Death Row Records striking Melissa Isaac while holding a knife in a parking lot near the Las Vegas Strip. They said Knight was carrying Ecstasy and hydrocodone when they arrested him.
Justice of the Peace Eric Goodman ordered Knight to receive counseling and pay a $340 fine. He's due back in court in August for a status check.
