The Vikings completed their preseason schedule with a home game against the Denver Broncos. To accommodate the Vikings playing in the 2010 NFL Kickoff game the following Thursday, this game was also played on a Thursday, and head coach Brad Childress opted to rest the majority of his starting lineup. As in each of their three previous preseason games, the Vikings conceded the first points of the game, allowing LenDale White to rush two yards into the endzone and convert on 2nd-and-goal. The Vikings were unable to earn a first down on each of their first three series, but after punting on the third, the Broncos' rookie quarterback Tim Tebow fumbled the snap on their return drive; Erin Henderson picked up the loose ball and returned it 35 yards for a touchdown. Ryan Longwell put Minnesota ahead with a 27-yard field goal on the first play of the second quarter, and from that point the Vikings never relinquished their lead. Albert Young then converted a 1st-and-goal from the 1-yard line to give Minnesota a 10-point lead at halftime. The two teams traded touchdowns in the third quarter, as Tebow threw a 39-yard pass to Matthew Willis for Denver, and Ian Johnson rushed 4 yards for Minnesota. A 14-yard pass from Brady Quinn to Alric Arnett brought the Broncos to within 3 points going into the last 12 minutes of the game, but on the very next series, Joe Webb threw a 63-yard pass to a wide open Javon Walker on the right side of the field, and the wide receiver walked into the end zone. Broncos kicker Matt Prater completed the scoring with a 49-yard field goal with just under 5 minutes left, giving the Vikings a 31-24 win and a 3-1 preseason record. Based on the NFL's predetermined scheduling formula, the Vikings will play every team in the NFC East and AFC East, the teams from the NFC South and NFC West that finished the same place in their division as the Vikings last year (which were the division winners), as well as their usual NFC North division rivals. The schedule was announced on April 20, 2010: the season began with the Vikings taking on the New Orleans Saints in the NFL Kickoff Game on Thursday, September 9, while the bye week will come in Week 4. The season will culminate with road games against the Philadelphia Eagles and the Detroit Lions.
