It was a rematch of the previous year's title game, and pitted two future Hall of Fame head coaches against each other, Tom Landry for the Cowboys and Vince Lombardi for the Packers.

Future hall of fame head coach Tom Landry of Dallas led his team to first place in the Capitol Division with a 9–5 record.

The Green Bay Packers, and future hall of fame head coach Vince Lombardi, won the Central Division with a 9–4–1 record.

[30] David Maraniss recounts in his 1999 Vince Lombardi biography When Pride Still Mattered that Packers safety Willie Wood left his home Sunday morning to find his car's battery frozen and dead.

The officials for the game found they did not have sufficient clothing for the cold, and had to make an early trip to a sporting goods store for earmuffs, heavy gloves, and thermal underwear.

Nothing was immune from the cold; at one point during the game, CBS commentator Frank Gifford remarked, "I'm going to take a bite of my coffee," as it too had frozen in the mug.

After missing a potential game-tying field goal, Green Bay scored the game-winning touchdown on its subsequent drive, re-gaining the lead, 21–17, with only 13 seconds remaining.

Aided by two Dallas penalties and a 17-yard reception from Donny Anderson, Green Bay opened up the scoring with an 83-yard, 16-play drive that took nearly 9 minutes off the clock.

Bart Starr detected a blitz coming on the Dallas 8-yard line, audibled, and rifled a touchdown pass to Boyd Dowler, giving the team a 7–0 first quarter lead.

Then on the second play of the Cowboys ensuing drive, defensive back Herb Adderley intercepted Don Meredith's pass and returned it 15 yards to the Dallas 32.

But after a run for no gain and an incompletion, Cowboys lineman George Andrie sacked Starr for a 10-yard loss, pushing Green Bay out of field goal range.

Then, with time almost out in the second quarter, Packers safety Willie Wood fumbled a Dallas punt after calling for a fair catch, and Cowboys rookie defensive back Phil Clark recovered the ball at the Green Bay 17-yard line.

The Packers were able to keep Dallas out of the end zone, but kicker Danny Villanueva kicked a 21-yard field goal to cut the deficit to 14–10 by halftime.

Later in the quarter, a 15-yard facemask penalty on Dallas rookie Dick Daniels during a Wood punt return gave Green Bay the ball on the Cowboys 47-yard line.

[49] Left guard Gale Gillingham pulled to his right like it was a typical sweep, and Cowboy right tackle Bob Lilly with his great reflexes instantly followed him.

The Packers' left tackle Bob Skoronski blocked Cowboy end George Andrie and Mercein shot through the hole to the 3-yard line.

[50] Twice Anderson attempted to run the ball into the end zone, but both times he slipped on the icy field before taking the handoff and was tackled inside the 1-yard line.

[54] Summerall told the rest of CBS crew to get ready for a roll-out pass, because without any timeouts remaining a failed run play would end the game.

[60][61][62] Kramer and center Ken Bowman executed a post-drive block (double-team) on left defensive tackle Jethro Pugh and Starr lunged across the goal line for a 20–17 lead.

[72] Green Bay went on to finish the postseason by easily[73] defeating the American Football League (AFL) champion Oakland Raiders, 33–14, in the second AFL–NFL World Championship Game.

Frank Gifford recounted in his 1993 autobiography The Whole Ten Yards that he requested and received permission from CBS producers to go into the losing locker room for on-air post-game interviews—a practice unheard of in that era.

The exhausted Meredith, in an emotion-choked voice, expressed pride in his teammates' play, and said, in a figurative sense, that he felt the Cowboys did not really lose the game because the effort expended was its own reward.

Gifford wrote that the interview attracted considerable attention, and that Meredith's forthcoming and introspective responses played a part in his selection for ABC's Monday Night Football telecasts three years later.

[77] [citation needed] Defensive tackle Bob Lilly took a different view, telling reporters that the Cowboys were a great team except that they could not win the "big one".

Wide receiver Lance Rentzel later remarked that on the team plane home from Green Bay to Dallas' Love Field, "not one word was spoken the entire flight."

With Green Bay having won five NFL championships in seven years[80] and the first two Super Bowls, Vince Lombardi retired as head coach of the Packers on February 1, 1968, but retained his position of general manager for the 1968 season.

In the three seasons following 1967, the Cowboys suffered two upsets in the playoffs to the Cleveland Browns, then lost Super Bowl V to the Baltimore Colts 13–16 on a last-second field goal.

Frank Clarke thought the Packers' final drive was "lucky football," though Chuck Howley acknowledged that the Cowboys' double coverage on the wide receivers left the backs open underneath.

Even Tom Landry in the NFL Film of the Ice Bowl stated that if he had realized the field was frozen, the Cowboys would have switched to a zone defense.

[91] A few months later, Lombardi assembled family members, friends and journalists to his home to watch The Greatest Challenge, the 1967 Packers season highlight film, which was produced by Ed Sabol and his son, Steve, and narrated by John Facenda.
