Coach Mike McCoy indicated Monday that there is a "possibility" that Mathews (ankle) could play Sunday against the Chiefs, Michael Gehlken of the San Diego Union-Tribune reports. While such an outcome is hardly a lock, the notion would be supported by a return to practice on the part of Mathews in the coming days. The running back has missed the Chargers' last two games, with his absence in that span having being filled by a backfield committee led by Branden Oliver, with Donald Brown and Ronnie Brown also in the mix.
