It may be the preseason, but the Chargers already are in midseason blackout-avoidance form.

San Diego’s NFL franchise has received a 24-hour extension of the deadline for selling all non-premium tickets to Thursday night’s preseason opener against the Seahawks. The Chargers have until 10:00 p.m. ET on Tuesday to sell the remaining tickets, which number roughly 1,800.

Some believe an extension isn’t provided absent assurances that any remaining tickets will be purchased by the team at 34 cents on the dollar.

The Chargers have struggled to sell tickets in recent years. Last season, the team opted not to take advantage of the rule that allows the threshold for lifting the blackout to be dropped to as low as 85 percent. The Chargers likewise opted not to reduce the minimum in 2013.
