The Cowboys started practice Thursday with Anthony Spencer on the field and stretching, but Dez Bryant on the side rehabbing.
It was the first practice of the week for Spencer, who said Wednesday that he still has discomfort in the knee where he underwent arthroscopic surgery in July.
Bryant rehabbed for a second practice, but unlike Wednesday, he was in a practice shirt, shorts and helmet.
Linebacker Ernie Sims also rehabbed.
