Smith caught his lone target for two yards in Saturday's 23-14 divisional-round playoff loss to the Chiefs.
Smith moved up the depth chart after Houston placed Cade Stover (collarbone) on injured reserve. Smith was a late-season addition to the active roster, as the Texans dealt with long-term and ephemeral injuries at the position, and was never targeted during the regular season. He enters the offseason as an unrestricted free agent.
