Pittsburgh sophomore starting safety Andrew Taglianetti will miss the rest of the season after tearing the anterior cruciate ligament in his left knee in Saturday's 54-27 victory at Buffalo.
Taglianetti, who established himself as a special teams ace last year, earned a starting job during fall camp at free safety. He had four tackles and a fumble recovery in Pitt's first two games.
"Our entire team is very disappointed for Andrew," Pitt coach Dave Wannstedt said in a statement. "He is an important performer on and off the field for us. The silver lining is he can receive a medical redshirt."
Pitt plays host to Navy on Saturday.
