Williams (ribs) has been ruled out for the remainder of Monday's game against the Chargers.
While being tackled by veteran linebacker Thomas Davis in the second quarter, Williams took a knee to the rib cage and spent multiple minutes on the ground. While he was eventually able to walk off the field under his own power, it's possible Williams will miss more action. In the meantime, LeSean McCoy and Darrel Williams will take over at running back for the remainder of Monday's game.
