ATLANTA - Dallas Cowboys linebacker Sean Lee is out because of a hamstring strain suffered in the first quarter against the Atlanta Falcons.
Lee missed two games earlier this season because of a hamstring injury. Lee missed the final five plays of Atlanta's second drive that ended in a Matt Bryant 50-yard field goal. Jaylon Smith will replace Lee in the base and nickel defenses.
In the two games Lee missed the season the Cowboys gave up an average of 164 yard rushing to the Los Angeles Rams and Green Bay Packers.
