Doss caught one of his five targets for eight yards in the 13-12 loss to the Chiefs on Sunday.
Doss had been on the Chargers' practice squad for a few years, and the 27-year-old finally got a chance to play thanks to injuries to Mike Williams (knee), Joshua Palmer (knee) and Keenan Allen (heel). It's entirely possible the wideout, who made his NFL debut in 2019, enters the offseason as an unrestricted free agent.
