IRVING -- The Cowboys returned to practice Monday after having the weekend off, and several key players injured players were back on the field.
Bennett arrived to practice with his jersey but no helmet, while Witten did have his helmet but didn't participate in an individual passing drill.
It was not determined how much those players participated in practice since the media only is allowed to watch the first 20 minutes of the session.
Bryant, Witten and Kosier were hurt in the Week 3 victory at Houston, but each player expects to play in Sunday's game vs. Tennessee.
Colombo, who missed the season opener after recovering from a scope in his right knee, was held out of practice mainly as a precaution last week because the Cowboys had a bye.
