The Patriots travelled to the Metrodome for a Monday Night Football showdown with the Minnesota Vikings, who, like the Patriots, boasted an excellent run defense. The Patriots, who took to the air with a spread offense for the entire game, opened with a seven-play, 86-yard strike that ended with a touchdown pass from Brady to wide receiver Reche Caldwell. Their next drive was for 93 yards which resulted in a 23-yard Gostkowski field goal. And just before halftime the Patriots moved 74 yards in 11 plays to take a 17-0 lead on a nine-yard scoring toss to tight end Benjamin Watson. The only Vikings score of the game came on a 71-yard punt return by Mewelde Moore in the third quarter; Laurence Maroney immediately answered on the ensuing kickoff, with a 77-yard return to Minnesota's 21-yard line, his second return of over 70 yards in as many weeks. The Patriots' lead grew to 17 after a seven-yard touchdown reception by Brown with 9:03 in the third quarter and then became 31-7 with a touchdown catch by Jackson. The Patriots defense also intercepted four passes from quarterbacks Brad Johnson and Brooks Bollinger. On Bollinger's first drive after relieving Brad Johnson he was sacked three times in a row for a net loss of 23 yards. With their fourth straight victory, the Patriots advanced to 6-1.This was the Patriots' third and final game played in the Metrodome.
