The Vikings started the regular season on the road against the Washington Redskins on September 11, the first game of a Monday Night Football doubleheader on opening weekend. The Vikings drew first blood as running back Chester Taylor ran in a 4-yard TD on their opening drive; however, during the extra-point try, holder Chris Kluwe fumbled the snap and instead tried to go for a two-point conversion, which failed. The Vikings lead was cut in half later in the quarter, as Redskins kicker John Hall made a 27-yard field goal. In the second quarter, things were starting to look grim for the Vikings, as Redskins running back Clinton Portis and kicker John Hall gave the Redskins a 5-yard touchdown run and another 27-yard field goal to make the score 13-6. The Vikings responded with a last-second 46-yard field goal from kicker Ryan Longwell as time ran out on the first half. In the third quarter, the Vikings continued their comeback as quarterback Brad Johnson threw a 20-yard touchdown pass to wide receiver Marcus Robinson to give Minnesota a 16-13 lead. However, the Redskins tied the game up on a 22-yard field goal by John Hall. Late in the fourth quarter, Longwell gave the Vikings a 19-16 lead, as kicked a 31-yard field goal. During the final minute of the game, the Vikings held their ground and hung on to give Brad Childress his first head coaching win, as opposing kicker John Hall missed a 48-yard field goal.
