The Chargers signed Doss to a reserve/future contract Tuesday, per the team's official site.
Doss, who failed to record an offensive snap for the second consecutive campaign, will stick around Los Angeles throughout the summer and into training camp where he'll eventually compete for a roster spot once again. The 26-year-old wide receiver joined the Chargers' practice squad back in October after being waived by the Giants at the end of the preseason.
