Mathews (ankle) is listed as questionable for Sunday's game against the Broncos, ESPN.com reports. Though Mathews did not practice all week, coach Mike McCoy suggested that the running back could still end up suiting up on Sunday. "He'll be fine," McCoy noted Friday. "He's played plenty of football in his career, and he knows what to do. He's been here. He's been in the system for the two years we've been here together, so he'll be fine." In any case, Mathews' status will be worth tracking closely in advance of Sunday's game, and it's possible that a final call on his status may not arrive until shortly before the Chargers' 4:05 ET kickoff. In the event that Mathews is out, or limited at all this weekend, Donald Brown, Branden Oliver and Ronnie Brown, to a lesser degree, would be in line to see added work in the Chargers' Week 15 backfield.
