The three former Ooltewah High School students convicted for their roles in the rape of a freshman player were sentenced in Sevier County Juvenile Court on Tuesday.
The sentencing hearing lasted for about two hours and was closed to the public.
A court order from the judge denied media coverage.
A source familiar with the case told WRCB-TV the oldest defendant, who is 18, will stay in custody until November 21. He has not been released from custody since his arrest in December.
The teen was convicted of aggravated rape and aggravated assault. He was 17 at the time of the incident.
Two other students, each convicted of aggravated assault, received an additional 60 days in a juvenile detention center.
Neither side would comment on what happened inside the courtroom.
