Penn State's defensive line depth has taken a hit as the team announced that redshirt freshman defensive end Pete Massaro will miss the 2009 season with a torn ACL in his right knee.
Massaro sustained the injury during Saturday's spring game and will undergo surgery in the next 2-3 weeks, according to team doctor Wayne Sebastianelli.
The Lions lost their top three defensive ends from last year's team in Aaron Maybin, Josh Gaines and Maurice Evans, who combined for 19 sacks and 31.5 tackles for loss. They can't afford many more injuries at a position that should be led by sophomore Jack Crawford this fall.
