Robinson did not receive any targets in Thursday night's 41-17 preseason win over the Chargers.
Despite playing 25 percent of the 49ers' offensive snaps, Robinson did not see a target in the contest. The 31-year-old had some positive traction in camp, working with the first-team offense last week. While the wide receiver has earned a fair share of reps in preseason play, it has yet to pay off with box score production.
