Maryland running back Da'Rel Scott and defensive back Nolan Carroll were involved in a violent collision on a run up the middle in Saturday's second scrimmage, and Scott is likely to miss the rest of the spring with a strained ACL.
Carroll went low to tackle Scott and his helmet collided with Scott's knee. Carroll was down on the field for about 10 minutes. He was immobilized by the training staff and taken to the hospital. Carroll had X-rays later in the day and the results were negative. He is expected to make a full recovery.
"Nolan Carroll had full use of his arms and legs, but he had pain in his neck so we had to be cautious," Friedgen said immediately after the scrimmage, according to the school's practice report. "He is experiencing concussion symptoms so he might be done for the rest of the spring. Hopefully he will be back."
The Terps have their spring game at 3:30 p.m. on Saturday, and Maryland fans won't be able to see their leading rusher.
"Dr. [Craig] Bennett thinks that Da'Rel Scott has a grade 1 ACL [strain]," Friedgen said. "So in two to three weeks he should be OK."
