Chargers running back Ryan Mathews (knee) has yet to be cleared to resume running, U-T San Diego reports.
"I'm just taking it one day at a time," Mathews said Wednesday. "When they think it's time for me to start running, then it's time to start running. It's all in their hands."
Mathews has been out for slightly longer than a month with an MCL sprain. The team has no reason to rush him back with Branden Oliver emerging as a threat at the running back position.
