Sensabaugh and Lee suffered concussions in the first half of the Cowboys win over the Redskins on Sunday.
The NFL has new guidelines a player must pass after suffering a concussion. Sensabaugh did some work in the walkthrough on Tuesday and when asked if he will play Saturday night at Arizona, he gave a thumbs up.
Roy E. Williams (groin) and Marion Barber. Williams (calf) did practice lightly. Williams did some pat-and-go during the open media session and Barber fielded punts, but it doesn't appear he will do so in any games.
