Sean Lee is out with a concussion

ARLINGTON, Texas -- The rookie year of second-round pick Sean Lee is almost as bad as first-rounder Dez Bryant's from a health standpoint.

Lee, the backup inside linebacker, is out with a concussion that was suffered on a second-quarter kickoff.

Lee missed the rookie minicamp waiting for his knee brace to arrive then he missed time in training camp with a quad injury. Once the season started he had hamstring and shoulder issues.

He was starting to come on strong, but with two weeks remaining in the regular season, it remains to be seen if Lee will return.

Kenwin Cummings, who joined the team on Dec. 8, moved into Lee's spot.
