The Bills Backers clubs will have a big presence at Sunday's Bills-Chargers game in San Diego. It wasn't enough, however, to ensure a sellout at Qualcomm Stadium. The Chargers announced about 5,000 tickets remain, and the game will be blacked out in Southern California. It's the second blackout of the season for the Chargers. The Bills have had one blackout so far, but are virtually assured of two more to close the season. The Chargers have one more home game after Sunday, vs. Baltimore, and that one is not yet sold out, either.
