The Oakland Raiders' game against the San Diego Chargers on Sunday will be blacked out on local TV.

The team announced that it had failed to sell out its stadium by Thursday's 4:15 p.m. ET deadline. It's the 10th straight blackout in Oakland and third this season.

NFL rules mandate that games which fail to sell out 72 hours before kickoff must be blacked out on local TV.

With the Raiders' and Buffalo Bills' blackouts on Sunday, the NFL will have had eight blackouts through five weeks. The league had 22 blackouts last season, a five-year high.

The Detroit Lions received a 24-hour extension on Thursday to continue selling tickets in an effort to avoid a blackout.

NFL rules allow teams to buy back tickets at about one-third the cost to avoid a blackout.

Since the Raiders moved back to Oakland in 1995, the team has had 64% of its home games blacked out.
