Lambert-Smith caught two of four targets for 14 yards in Thursday night's 41-17 preseason loss to the 49ers.
Lambert-Smith also returned two punts for 15 total yards. The wide receiver played 34 percent of the Chargers' offensive snaps, garnering a decent amount of attention for the time he was on the field. The second-year player out of Auburn is fighting for position in the team's wide receiver corps, with Ladd McConkey, Quentin Johnston (lower body), Tre' Harris (undisclosed) and Brenen Thompson all currently set to see more snaps.
