Thompson caught one of two targets for nine yards in Thursday night's 41-17 preseason loss to the 49ers.
Thompson was targeted six times in last Thursday's contest against the Texans. The rookie fourth-rounder did not see much action against the 49ers, with both targets taking place in the first quarter before the wide receiver was ushered out of the game. Thompson played just nine snaps in the contest, totalling 15 percent of the Chargers' total offensive plays.
