Cowboys unsure of Sean Lee's effectiveness

IRVING, Texas -- Inside linebacker Sean Lee was limited in Thursday’s practice but he expects and the Cowboys expect him to be able to play Sunday against Buffalo barring a setback.

Lee is wearing a cast that covers his fingers, which leads you to wonder just how effective he can be.

“I don’t know that you know,” coach Jason Garrett said. “Again, you make your best assessment of the situation, factor in what he was able to do in the past, watch him this week in practice, what kind of guy he is and how he looked, and you put it all together and make your best judgment.”

Several players have worn these types of casts in games, including Patrick Willis last year in San Francisco because of a broken hand. Lee is dealing with a dislocated left wrist.

Last year the coaching staff was upset with Lee after he suffered an injury on a kickoff in the season opener and did not tell anybody.

“Their opinion about their injury matters, the mindset they have, the willingness to play is important,” Garrett said, “but having said that you have to process those things as a coach and medical staff and out it all together and make our best decision. You want guys who want to play but at the same time you have to make evaluations and see if they can play as well as we need them to play.”

Right guard Kyle Kosier returned to practice on a limited basis Thursday after sitting out Wednesday’s workout with plantar fasciitis. He said he would play Sunday against the Bills. Backup tackle Jermey Parnell was also limited in practice after missing the previous day with a sore back.

Cornerback Mike Jenkins (hamstring), wide receiver Miles Austin (hamstring) and running back Felix Jons (ankle) did not practice.
