Claiborne and Harris injured their hamstrings in last week's victory over the New York Giants.
All four players could return when Dallas faces Chicago on Dec. 9. The Cowboys don't play for 10 days after facing the Raiders.
Rookie tight end Gavin Escobar was added to the injury report Wednesday with a hamstring issue and is listed as questionable. The Cowboys have six players with hamstring problems.
Linebacker DeVonte Holloman, another rookie, will miss his sixth straight game with a neck injury.
