Chargers QB Rivers reports possible concussion symptoms

COSTA MESA, Calif. (AP) — Los Angeles Chargers quarterback Philip Rivers is in the NFL’s concussion protocol after experiencing possible symptoms of a head injury, endangering his streak of 194 consecutive starts since 2006.

Rivers told the Chargers about his symptoms Monday after they returned from a 20-17 overtime loss in Jacksonville, coach Anthony Lynn said. The Chargers (3-6) are still hopeful Rivers can play on Sunday when they host the Buffalo Bills, but they will be cautious with the health of one of the most durable quarterbacks in NFL history.

“He needs to pass the test first,” Lynn said. “If he’s not healthy, we do not want him on the field. But if he’s healthy and ready to go, then (he’ll play).”

Rivers wasn’t sacked by the Jaguars, but he was hit five times and pressured regularly. Lynn wasn’t certain when Rivers was hurt, but the quarterback took a big shot when he threw a long interception in overtime.
