Allen is dealing with a sore throat and has tested negative for COVID-19, but his availability for Sunday's game against the Raiders remains up in the air, Adam Schefter of ESPN reports.
The 28-year-old was added to the injury report Saturday and is officially considered questionable. Allen will need to pass additional COVID-19 testing to have a chance of suiting up Sunday. According to Schefter, the Chargers still hope the veteran wideout will be able to play but are preparing as though he'll be unavailable. Mike Williams and Jalen Guyton would lead Los Angeles' wide receivers if Allen is unable to suit up.
