There has never been a Super Bowl game without a touchdown scored by either team.
There has, however, been a title game where one team failed to score a touchdown: the 1971 Dolphins, who lost 24–3 to the Dallas Cowboys in Super Bowl VI at Tulane Stadium in New Orleans, La.
Miami's three points came from a field goal in the second quarter before the Dolphins were shutout entirely in the second half. The Cowboys tallied two more touchdowns after halftime to secure Dallas's first-ever Super Bowl championship.
One season later, the Dolphins were also part of the lowest-scoring title game in NFL history.
