FRISCO -- When Cowboys ninth-year linebacker Sean Lee pulled up during Monday night's game against Tennessee, grabbing his left hamstring, it was all too familiar a sight.
Try as he might, Lee has not been able to solve the hamstring issues or injuries that have plagued his career. He already missed three games earlier this season to the strained hamstring. He's expected to miss another four-to-six weeks now.
While the Cowboys are better equipped to handle Lee's absence than perhaps ever before because of the play of linebackers Jaylon Smith and Leighton Vander Esch, defensive coordinator Rod Marinelli said it's hard to see Lee injured again.
"I know what it means to him, the game of football," Marinelli said. "I don't know if I've ever been around a guy who prepares harder, is more locked in every single day, and how much it means to him. This thing means everything to him.
