On December 5, 2010, the Raiders defeated the Chargers, 28-13, at San Diego. It gave Oakland a rare season's sweep over their longtime rivals in Southern California. Earlier, Chargers hadn't lost a regular-season game to the Oakland Raiders since September 28, 2003 at Oakland -- a streak of 13 games. But on October 10, 2010, the Raiders upset the Chargers, 35-27, with two touchdowns in the final four minutes.
The Raiders defeated the Eagles, 27-10, in Super Bowl XV played January 25, 1981.

On January 22, 1984, the Los Angeles Raiders defeated the Washington Redskins in Super Bowl XVIII in Tampa, 38-9.
