Morgan tore his left ACL during Tennessee's fourth game as a rookie, and he had been cleared before training camp. But the former Georgia Tech star felt something in the knee during the Titans' second preseason game at St. Louis.
Coach Mike Munchak said Tuesday that Morgan had the surgery when he visited Dr. James Andrews on Monday in Alabama. Andrews performed the original surgery on Morgan's knee.
Munchak called it a small setback for Morgan, who could miss as many as three weeks.
