SAN DIEGO -- Chargers quarterback Philip Rivers split snaps with his backup during practice Friday and is questionable for San Diego's home game Sunday against the Detroit Lions because of a sprained knee.
Rivers sprained his left knee in Sunday's overtime win at Tennessee and didn't practice Wednesday. He shared the quarterback duties with Billy Volek on Thursday and Friday, and hopes to be ready for the Lions.
"That's the plan and what I'm shooting for," Rivers said.
"We'll see what happens."
San Diego (8-5) can clinch the AFC West title for the second straight year by running its winning streak to four games Sunday.
If Rivers can't go, Volek would make his 11th NFL start and first as a Charger. He is 3-7 as a starter.
