Farmer, from Garfield Heights, Ohio was sentenced to three years in prison for kidnapping and assault of his ex-girlfriend Andrea Lane.
The 18-year old basketball star looked shocked when his sentence was announced by the judge before he turned to his attorney and collapsed to the floor after fainting.
Farmer, a 6-foot-6 forward, was ranked as one of the top-100 high school players in the class of 2013 and was being courted by the likes of Dayton, Xavier, Ohio State, Michigan State, Iowa, West Virginia and Illinois.
His sentence will be reviewed after 180 days and the schools will have to wait and see how the case plays out, according to the Cleveland Plain Dealer.
The incident took place last April in the lobby and parking lot of Farmer's apartment complex. It was caught on a building security camera. Farmer also reportedly threatened Lane via text messages.
