“It was about our defence’s effort tonight,” said Vikings coach Kevin O’Connell, whose side were 13-0 up at half-time.
“It just felt like when we needed a play, those guys made it.”
Elsewhere, Atlanta Falcons quarterback Kirk Cousins ended his four-game touchdown pass drought as the Falcons held on to beat the Las Vegas Raiders 15-9.
The win for the Falcons was their first in four games, improving them to 7-7, behind the Tampa Bay Buccaneers who are 8-6, in the NFC South.
Cousins had failed to throw a touchdown pass since 3 November, but against the Raiders, he passed for 112 yards with one interception and provided Drake London with a touchdown in the first quarter.
“It’s not where I want it to be,” said Cousins. “There’s a lot of room for improvement.”
The Raiders were still threatening late, but quarterback Desmond Ridder failed to connect on two passes into the end zone in the last 10 seconds.
