They may be America’s Team and they may be one of the most recognizable sports franchises in the world, but the Dallas Cowboys haven’t beaten the Denver Broncos in over 20 years.

Yes, the teams meet just once every four years, but the Broncos still hold a five-game winning streak over the Cowboys and hold a 7-5 edge in the all-time series.

The Broncos will look to make it six in a row over the Cowboys when they face Dak Prescott, Ezekiel Elliott and Co. on Sunday at Sports Authority Field.

Let’s take a look back at some of the memorable matchups between these two teams.

January 15, 1978: Cowboys 27, Broncos 10: Super Bowl XII at the Superdome in New Orleans. The Broncos were somewhat of a surprise participant going up against Tom Landy, Roger Staubach and the rest of the Cowboys, who were making their fourth Super Bowl appearance in eight years. The Cowboys dominated the game, winning 27-10 while Broncos quarterback Craig Morton had one of the historically bad Super Bowl performances. He threw four interceptions in the game and completed just four passes.

September 11, 1980: Broncos 41, Cowboys 20: This was the first time the Broncos defeated the Cowboys. The dominant 21-point victory took place at Mile High Stadium and included four rushing touchdowns for the home team.

September 10, 1995: Cowboys 31, Broncos 21: This is the last time the Cowboys were able to beat the Broncos. Dallas was led by Troy Aikman, Emmitt Smith and Michael Irvin. Smith rushed for 114 yards and Irvin caught six passes for 94 yards.

September 13, 1998: Broncos 42, Cowboys 23: This game took place during the Broncos’ magical 1998 Super Bowl year. Terrell Davis had one of the best days of his career, rushing for 191 yards while scoring on running plays of 63 and 59 yards. He finished with three touchdowns.

November 24, 2005: Broncos 24, Cowboys 21, OT: For the fans that watched this Thanksgiving Day showdown, the game didn’t disappoint. A 55-yard scamper by Broncos running back Ron Dayne set up Jason Elam’s game-winning field goal from 24 yards out.

October 4, 2009: Broncos 17, Cowboys 10: This game came during the Josh McDaniels era and likely came as a bit of a surprise as the Broncos seemed outmatched by the Cowboys, at least on paper. Denver got the win after Kyle Orton threw a 51-yard touchdown pass to Brandon Marshall with less than two minutes to play. The Broncos improved to 4-0 on the season with the victory.

October 6, 2013: Broncos 51, Cowboys 48: The most recent meeting between these teams and arguably the most memorable. This game turned into a shootout at AT&T Stadium and wound up being one of the highest-scoring games in NFL history.

The Broncos came into the game at 4-0, but the Cowboys jumped out to a 14-0 lead. Peyton Manning would rally his troops though, throwing for four touchdowns in the game. Statistically, Cowboys quarterback Tony Romo had an even better day, tossing five touchdown passes while racking up 506 yards through the air. A late interception of Romo by Danny Trevathan would set up a game-winning field goal from 28 yards out by Matt Prater.
