Tennessee quarterback Erik Ainge underwent successful surgery on his right knee Monday and has been released from UT Medical Center. Head Athletic Trainer Jason McVeigh reports that the torn meniscus cartilage was removed and he expects Ainge to make a recovery to full activity within 3-6 weeks. The Vols conclude their spring practice with the EdAmerica Orange and White Game on March 31. “This injury to Erik is not expected to impact the 2007 season or his long-term health in any way,” McVeigh said. Drs. Greg Mathien and Russell Betcher of the Knoxville Orthopedic Clinic performed the surgery. Tennessee returns to practice this week with workouts Tuesday, Thursday and Friday, followed by a Saturday scrimmage in front of the annual coaches clinic attendees.
