Dallas Cowboys defensive coordinator Rod Marinelli has revealed that Sean Lee has been overwhelmed with excitement on his return to the field.
The 28-year-old missed the 2014 season after tearing his ACL during his side's first practice session last year, but has overcome the injury to return for the Cowboys' organised team activities.
"He's a ball of energy and excitement and that represents who we are," Marinelli told reporters.
"He's moving well. We're just being smart as we get him ready to go. But he's got a lot of good quality work in."
Lee has recorded 294 tackles and 11 interceptions in his five years in the NFL.
