Sean Lee practiced again Thursday, and coach Jason Garrett said the team was "certainly optimistic" that the linebacker would play on Sunday against Green Bay.
It was again a non-padded practice.
Returner Dwayne Harris, cornerback Morris Claiborne and linebacker Bruce Carter, all recovering from hamstring injuries, missed practice, but they joined the team on the field. Claiborne returned to the facility after going home last week following the death of his father.
