With roughly 8,000 general admission tickets still unsold, the Chargers expect Sunday's home opener against the Jaguars to be blacked out.
That will end a streak of 48 straight sellouts, including the playoffs.
The last Chargers home game blacked out was against New Orleans on Nov. 7, 2004.
"We're disappointed, but from a couple weeks out we thought this was a possibility," executive vice president A.G. Spanos said.
