Chargers running back Ryan Mathews did not practice Thursday, according to U-T San Diego.

Mathews sustianed a concussion during last week's loss against Oakland. He's yet to be cleared and will have to pass the NFL's protocol before playing this Monday against Indianapolis.

Though Mathews is unable to practice, left tackle King Dunlap was cleared to return practicing after passing his concussion exams.
