Cowboys LB Sean Lee leaves Sunday's game with possible concussion

Cowboys linebacker Sean Lee left Sunday's game against the Saints during the first half to be evaluated for a possible concussion, ESPN's Todd Archer reports.

Lee's had a hard time staying healthy in recent seasons, but he hasn't missed time due to a concussion since 2010. Any absence would be a massive hit to the Dallas defense, as Lee is making an early case for DPOY consideration.
