54 Years: Vikings' Loss Extends 1972 Dolphins' Unbeaten Record

Larry Csonka, a member of the 1972 Miami Dolphins, celebrated the extension of the team's 54-year undefeated record on Sunday.

The 1972 Dolphins finished their season with a 17-0 record, including a victory in Super Bowl VII. This performance remains the only perfect campaign in the Super Bowl era, which began in 1966. The New England Patriots came closest to breaking the record in 2007, reaching 18-0 before losing to the New York Giants in Super Bowl XLII. In 2024, the Kansas City Chiefs entered Week 11 unbeaten before suffering a loss. The Minnesota Vikings held the league's only remaining undefeated record entering Week 8 of the 2026 season, standing at 6-0.

On Sunday, the Vikings lost 19-15 to the Detroit Lions. This result confirmed that no team would complete an unbeaten season in the current campaign. Csonka posted an image on social media showing himself raising a glass while holding a cigar and wearing his Super Bowl ring. He wrote that the Dolphins' record now stands at 54 years. The fullback also congratulated the Lions on their win.

During the 1972 season, Csonka led the Dolphins in rushing with 1,117 yards and scored six touchdowns. In Super Bowl VII, he rushed for 119 yards, including a 49-yard run.
