Hartsfield, a senior who has started all nine games this season, suffered the injury on a running play with 2:20 remaining in the second quarter of Saturdays game against Georgia Tech.
This is another tough loss for the program, Edsall said. Demetrius is a captain and has been a leader of this defense both on and off the field. I feel terrible for him because I know how much the game means to him. To have his senior year cut short is just disheartening. We will be here to support him through the rehab process and help him with his transition towards the next stage of his career.
Hartsfield leads the team with 78 tackles this season. He has also totaled seven tackles for loss, 3.5 sacks, one interception and two fumble recoveries. His 338 career stops rank 10th nationally among active players and 15th in school history.
