WR Andre Johnson back in lineup

Houston Texans receiver Andre Johnson will return to his starting job after taking every snap in practice this week.

He's been out for six games with a hamstring injury.

Free safety Danieal Manning will also return to the starting lineup at Jacksonville after missing time with an ankle injury.

Coach Gary Kubiak said they will count Manning's plays. He will start but he won't take every snap.

Fullback Lawrence Vickers hasn't practiced all week because of a hamstring injury, but Kubiak said he will be a game-time decision on whether he plays. He's questionable.

Defensive end Tim Bulman (calf) and tight end Garrett Graham (hamstring) were limited in practice and are questionable. Kubiak said they will also be game-time decisions.
