Dallas Cowboys middle linebacker Sean Lee was ruled out for Sunday's game against the Green Bay Packers with a neck injury.

A magnetic resonance imaging exam discovered a sprained neck ligament, according to ESPN Dallas.

Justin Durant will start in place of Lee, who got hurt against the Chicago Bears.

"Whenever you're talking about head and neck, you're particularly careful, there's no question about that, particularly about a guy who has as much contact as he does," coach Jason Garrett said. "Having said that, you try to evaluate the injury as best you can with the scans that you do with all of that and what the player is saying, his willingness, his demeanor, his mindset and all of that stuff, and you put it all together and try to make the best decision."
