Once was nice, and twice was ice for Patrick Peterson.

The Vikings cornerback's first interception of Josh Allen occurred in the end zone and helped spark a furious fourth-quarter comeback by Minnesota.

His second of the day — in overtime and again in the end zone — secured a 33-30 victory for Minnesota, which claimed its seventh consecutive win, improved to 8-1 on the season and added an uber degree of legitimacy for the team's detractors to try to take down.

For the second week in a row, Minnesota overcame a 10-point deficit in the fourth quarter on the road.

Peterson sent the Vikings to the airport with another win by stepping in front of a pass intended for Gabe Davis with just more than a minute left in overtime. The play had started at the Minnesota 20, with Buffalo already within range to try to tie with a field goal.

Greg Joseph had given Minnesota the three-point lead with 3:42 remaining in the 10-minute period after an impressive drive by the Vikings that opened with a 60-yard drive that lasted 6:18.

Minnesota began chipping away at a 17-point lead by Buffalo late in the third quarter when Dalvin Cook ripped off an 81-yard touchdown after Buffalo had built a 27-10 edge with a field goal by Tyler Bass.

The Bills looked ready to answer and expand their lead but opted to throw on fourth-and-2 from the Minnesota 7-yard line. Peterson thought otherwise, nabbing his first pick of the day and returning it to the 34-yard line.

The Vikings built on momentum, eventually finishing a 66-yard drive with a 3-yard run by fullback C.J. Ham to make it a 27-23 game with 4:34 left in regulation.

Minnesota forced a quick punt and drove the ball again, but Kirk Cousins was stopped inches shy on a sneak on fourth-and-goal with 49 seconds remaining.

Allen fumbled the snap on the following play, and Eric Kendricks recovered the ball in the end zone for a 30-27 lead with 41 seconds left.

Buffalo quickly drove for a 29-yard field goal with two seconds remaining to force overtime.

Minnesota opened the extra session with gains of 10 and 9 by Cook. Justin Jefferson pulled in a 24-yard reception and drew a 19-yard pass interference penalty, but the Vikings settled for Joseph's 33-yard field goal, which proved to be enough.

Peterson has played Buffalo just four times in his storied career. He had an interception in each of the previous three games and lifted his total against the Bills to five.

Here are four more observations presented by Minnesota Eye Consultants, the Proud LASIK Partner of the Minnesota Vikings, followed by a scoring summary:

1. Jefferson & Diggs both bring it; Dalvin does, too

The Vikings drafted Justin Jefferson in 2020 with a pick received for sending Stefon Diggs to Buffalo.

Both star players brought their "A" games Sunday.

Jefferson finished with a career-best 193 yards on 10 catches. His day included receptions of 46 and a 22-yard score on Minnesota's first possession.

But the best was when the Vikings needed it most. Jefferson won a 50-50 ball as players were heading to the ground for a gain of 32 on a fourth-and-18 on the play after regulation's 2-minute warning. The majestic reception took the ball from the Minnesota 27 to the Buffalo 41.

Jefferson set a record for the most games with 100-plus receiving yards in a player's first three seasons with his 20th such performance in his by recording his 20th game with at least 100 receiving yards in his 42nd career game. He topped 19 by Randy Moss and Odell Beckham, Jr. Jefferson also recorded his seventh game with 150 or more yards, topping a record set by Moss and Lance Alworth for the most such games in a player's first three seasons.

Diggs finished with 128 yards on a game-best 12 catches, but the Vikings defense limited his longest gain to 25.

Diggs also had an incredible one-handed catch on his highlight reel.

The game also was special for Cook, who finished with 119 yards on 14 carries, and faced his younger brother James for the first time. Minnesota was able to limit James to 22 yards on five carries.

2. Cousins overcomes mistakes

Cousins finished 30-of-50 passing for a season-high 357 yards. He had the touchdown to Jefferson early before suffering a pair of picks.

The first was a deep shot overthrown down the middle of the field late in the first quarter.

The second was under duress and seemed to occur because of a bit of indecision between trying to get the ball to Jefferson or take a safety valve throw to Thielen near the line of scrimmage.

But when the game was on the line, Cousins found a way to be at his best and pinpoint key throws to Jefferson.

The Vikings dealt with the loss of T.J. Hockenson for a bit while the tight end was evaluated after a helmet-to-helmet hit that wasn't flagged. Minnesota also needed to lean on reserve Blake Brandel at left tackle after Christian Darrisaw left the game.

3. Defense remains about the ball

Kevin O'Connell promised his defense would be about the ball when he was hired. It was again Sunday, totaling four turnovers.

The Vikings allowed 486 yards in the shoutout but only three touchdowns to an explosive Bills offense.

Camryn Bynum recovered a fumble forced by Akayleb Evans that halted a Buffalo drive in Minnesota territory with 3:15 remaining.

Peterson's first interception stopped a drive that covered 67 yards, and the second one ended the game after 52 yards had been gained by Buffalo.

The least probable, however, was Kendricks' alert fumble recovery. He stormed in after former Bills defensive lineman Harrison Phillips created a surge at the line of scrimmage.

The Bills were trying to execute a QB sneak with the ball inside their own 1-yard line after a stand by their defense had kept Cousins just shy of the line to gain on fourth-and-goal.

Kendricks recovered the fumble in the end zone for a touchdown.

4. Outlasting Allen

Allen turned in a gritty performance after an elbow injury last week.

He completed 29 of 43 passes for 330 yards with one touchdown, two interceptions and a passer rating of 78.6.

Allen did even more damage on the ground, leading the Bills with 84 yards on six runs.

But the Vikings defense was able to outlast the young star.

Despite losing Evans, who was already filling in for Cameron Dantzler, Sr., at the cornerback spot opposite Peterson, Minnesota was able to limit Allen to a long pass of 25.

Rookie Andrew Booth, Jr., logged his first significant action on defense, and Duke Shelley, who had been elevated from the practice squad Saturday, delivered a pass breakup on a throw to Dawson Knox in the end zone one play before Peterson's game-winner.
