Trying to snap a five-game skid, the Raiders flew to the Hubert H. Humphrey Metrodome for a Week 11 interconference duel with the Minnesota Vikings, as QB Daunte Culpepper would be getting the start against his former team. In the first quarter, Oakland trailed early as Vikings RB Chester Taylor managed to get a 10-yard TD run, along with a safety (due to Culpepper committing a penalty while in his own endzone).  The Raiders would get on the board as kicker Sebastian Janikowski managed to get a 42-yard field goal.  In the second quarter, Minnesota increased its lead with kicker Ryan Longwell getting a 30-yard field goal.  Afterwards, Oakland would take the lead as Culpepper completed a 10-yard TD pass to TE John Madsen, along with Janikowski kicking a 30-yard field goal.  The Vikings would answer with Taylor getting a 38-yard TD run.  Fortunately, the Raiders would tie the game heading into halftime as Janikowski kicked a 42-yard and a 49-yard field goal. In the third quarter, Minnesota regained the lead with Longwell kicking a 38-yard field goal for the only score of the period.  In the fourth quarter, the Vikings ended its scoring day with Taylor getting a 6-yard TD run.  Oakland tried to come back as Janikowski nailed a 52-yard field goal.  However, Minnesota would hold on for the win. With their sixth-straight loss, the Raiders fell to 2-8, securing the team's fifth consecutive non-winning season.
