Brandon Adams, a rising senior who was expected to be a key member of Georgia Tech’s defensive line under new coach Geoff Collins, died at the age of 21, the school announced Sunday.

Adams had been going through off season workouts and was preparing for the start of spring practice when he died on campus Saturday. No cause was given.

The Georgia Bureau of Investigation was assisting and its medical examiner’s office said an autopsy would be conducted Monday, a day before the Yellow Jackets are scheduled to hold their first practice of spring.
