Sean Lee ComebackWhen the Nittany Lions kick off preseason practice Aug. 10, it will have been 16 months since Lee previously took part in full-contact drills. And by the time the fifth-year senior co-captain from Upper St. Clair High School finally slips on his No. 45 jersey for the Sept. 5 non-conference opener against Akron, it will have been more than 20 months since he last played in a game.No player on Penn State's roster is more eager for the start of two-a-day practices than Lee, who had surgery to repair a torn anterior cruciate ligament in his right knee in April 2008. Now he is a nervous bundle of energy who admits he has struggled to control his emotions. "I can't wait to be playing football again, smelling the grass in August, putting the pads on, getting the little nicks on your nose from hitting, busting your fingers a little bit," he said. "I just am ready to go through it again. "Whenever I look at the [preseason] magazines or anything college football, thinking about the season, I get hyped up, worked up. Sometimes, if College Football Live is on [ESPN], I have to change the channel because my adrenaline starts running so much." Lee, 6 feet 2, 236 pounds, was primed for a big senior year last season. As a junior, he was named a first-team All-American by Pro Football Weekly and finished second in the Big Ten Conference in tackles (138) behind former teammate Dan Connor. Lee also was named defensive MVP of the Alamo Bowl in December 2007 and NFLDraftScout.com ranked him as the top outside linebacker in the 2009 NFL draft, as well as the No. 6 player overall. But those projections were cast aside when Lee was injured while blitzing quarterback Daryll Clark in a scrimmage April 11, 2008.Penn State's Sean Lee, right, with Maurice Evans during a football practice at State College in March of 2008.
