Murray originally was listed as questionable but was able to go through three limited practices leading into kickoff.
Murray suffered a sprained medial collateral ligament in his knee two weeks ago against the Washington Redskins. According to a source, Murray did not suffer a setback in his recovery.
The Cowboys also were without defensive end DeMarcus Ware for the second straight game because of a quadriceps strain.
Wide receiver Miles Austin did not play because of a hamstring injury. He played the previous two games but did not have a catch against the Redskins or Eagles. Rookie Terrance Williams, who has a touchdown catch in three straight games, replaced Austin.
