The Chiefs held on to their 14-0 lead as Kyle Boller threw his third interception at the Oakland 12-yard line on a telegraphed pass intended for Darrius Heyward-Bey.
Moments earlier, Boller had hit Heyward-Bey for a 21-yard gain and scrambled 19 yards to the Chiefs 36 as the Raiders threatened for the first time since Michael Bush got stuffed on a fourth-and-1 play off a direct snap.
The Raiders had five penalties and four three-and-out possessions to go with three interceptions by Boller.
Darren McFadden missed much of the first half with an undiscclosed injury.
The half ended with safety Chinedum Ndukwe interception a desperation pass at the 1-yard line and the Raiders (or Boller) being booed off the field.
