Hartsfield, a senior from Raleigh, N.C., suffered the injury on a running play with 2:20 remaining in the second quarter of Maryland's 33-13 loss to Georgia Tech. Hartsfield, who was blocked low on the play, had started all nine games this season.
“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.”
The Terps' leading tackler with 78 stops, Hartsfield has also contributed seven tackles for loss, 3.5 sacks, one interception and two fumble recoveries this season. His 338 career tackles rank 10th nationally among active players, and 15th in Maryland history.
