Losing by 42 points to the lowly Raiders was apparently the last straw for Brandon Staley in Los Angeles ... 'cause the Chargers just revealed they've fired their head coach after the embarrassing defeat.
The final decision came down on Friday morning, less than 24 hours after the Staley-led Chargers were whooped, 63-21, in Las Vegas.
Bolts honcho Dean Spanos announced in addition to giving Staley the axe, he's also booting general manager Tom Telesco following the historic L as well.
"I want to thank Tom and Brandon for their hard work, dedication and professionalism, and wish both them and their great families nothing but the best," Spanos said.
