On December 23, the Chiefs visited the Oakland Raiders for a Saturday night game.  The game was broadcast on the NFL Network and local Oakland and Kansas City television at 5pm Oakland time.  Former Chiefs head coach Dick Vermeil helped announce the game with Bryant Gumbel on NFL Network.  The Chiefs had lost three straight and the Raiders lost seven in a row.  The Raiders themselves had not beat the Chiefs in four years and were looking for their first division win since 2004. Kansas City managed to hold Oakland throughout the first quarter while Lawrence Tynes managed to get a 29-yard field goal.  Kansas City's Jared Allen recovered a fumble from Oakland's Andrew Walter after Walter was sandwiched by Allen and Kawika Mitchell.  In the third quarter, the Raiders would get yet another field goal as Janikowski got one from 53&#160;yards out.  It would be the final score from Oakland of the night, and the third field goal.  Kansas City looked to extend their lead with a kick from Lawrence Tynes but the kick was missed wide right.  Kansas City still had the lead, 17-6. The Chiefs became the first team to ever win eight straight against the Raiders.  The Raiders (2-13) have lost eight straight overall and matched the franchise record for losses in a season set when they went 1-13 in 1962&#8212;the season before Davis arrived to coach and eventually own the team. Larry Johnson has 398&#160;yards rushing in three starts against the Raiders, and his 10 touchdowns in six games are his most against any opponent.  Johnson broke Christian Okoye's club record of 370 carries in a season. Johnson's 31 carries gave him 383.  With the win, Kansas City snapped its three-game skid, improved its record to 8-7, while the Raiders lost their eighth straight game of the season.
