Sean Lee fitted for a cast

IRVING, Texas -- The chance of Sean Lee playing Sunday against Seattle remains slim, but the Cowboys are fitting the linebacker for a cast for his dislocated left wrist.

"Typically what happens is there are a lot of different iterations of that thing. What is comfortable? What feels good?" Garrett said. "And you kind of keep working through those kinds of things."

Lee, who suffered the injury on the final play of the first quarter against Philadelphia, missed his second straight day of practice on Thursday and he will not practice until the swelling subsides. And even then there is a chance he will not have enough strength to play. According to a league source familiar with such injuries, if Lee requires surgery, then he would miss the rest of the season.

In 2009, Chicago linebacker Brian Urlacher dislocated his right wrist in the season opener and missed the rest of the season.
