Colston, the team's all-time leading receiver, has a chest injury that also sidelined him for New Orleans' victory over Jacksonville last Sunday.
Colston finished with 45 catches for a career-low 520 yards and four touchdowns, including a 53-yard score, in 13 games this season. Those numbers represent a substantial decline from most of his career, which includes six seasons eclipsing 1,000 yards, two others surpassing 900 and a previous low of 760 yards when he missed five games. His current contract runs through next season.
