Bryant complained of soreness following the special teams portion of practice, and Cowboys officials kept him out the rest of the day.
Cowboys coach Wade Phillips, who called Bryant's injury "slight," believes the wide receiver will play in Sunday's road game against the Houston Texans.
Phillips said Witten participated in contact drills three days after he wasn't allowed to play the final 8:05 in the 27-20 loss to the Chicago Bears as a precaution because of a slight concussion.
There is no doubt about Witten's availability for Sunday's game in Houston.
Jenkins, who bruised his right knee against the Bears, did not participate in contact drills. He is expected to start Sunday.
Nose tackle Jay Ratliff also was absent Wednesday because he was to attend the Thursday funeral of his grandparents, who died in a house fire last week.
Phillips said Ratliff will play in Sunday's game.
