Sean Lee doubtful; Mat McBriar punting

IRVING, Texas -- The Cowboys were in full pads, and former guard Larry Allen was watching practice Wednesday at Valley Ranch.

In terms of personnel, inside linebacker Sean Lee wasn't on the field during the 20 minutes the media is allowed to watch practice. Lee is getting a second opinion on his dislocated left wrist, which still has swelling. It's doubtful he'll play on Sunday against the Seattle Seahawks, and if he undergoes surgery he'll miss six to eight weeks.

Punter Mat McBriar, who has nerve damage in his left foot, did some punting during practice. However, Chris Jones was re-signed to the practice squad Wednesday as precaution for McBriar, who couldn't finish Sunday's game against the Eagles because his foot was giving him trouble.

Running back Felix Jones (ankle) and cornerback Mike Jenkins (hamstring) also missed practice.

Guard Kyle Kosier has a partially torn plantar fascia in his left foot. He was limited during the practice session.
