The Boston Red Sox and New York Yankees. The Dallas Cowboys versus the Washington Redskins. And in Wednesday's case, even Duke versus North Carolina.
These are all great rivalries in the world of sports, but one commonly gets left out.
While the rivalry is typically reserved for just the late rounds of the Olympics or the gold-medal match, women's hockey fans will be given a treat on Day 5 as Canada and USA will face off in the final game of the preliminary round of the 2014 Winter Olympics.
After both dominated their way to a guaranteed spot in the next round of competition, the No. 1 and 2 teams in the world will fight to decide who claims the higher seed in the tournament moving forward.
U.S. forward Monique Lamoureux spoke about the rivalry and helped put it in perspective, per Kevin Allen of USA Today:
Any game against Canada, whether you are playing in Timbuktu, with no one in the stands, or playing in front of 12,000 or 15,000 people, you get up for it. ... We want the No. 1 seed, but any game against Canada, we will be ready for it.
With that type of excitement heading into the game, it should be a grueling matchup on the ice.
Before the two teams face off in what is sure to be an Olympic classic, here is a look at all the information fans need to know about the game.

Breakdown of USA vs. Canada
Here's what we know: Since 1990, USA and Canada have competed in every gold-medal game—World Championships or Olympics. USA defeated Canada the last two times they faced and had to go to a shootout to win their most recent match.
As for their results so far, both teams have thoroughly dominated their competition through two games against Finland and Switzerland.
Canada hasn't allowed a goal thus far and has won by a combined total of 8-0, but it struggled to score against the Finns before scoring all three goals in the final period.
The U.S. has allowed one goal, but it came in garbage time against Finland after holding a 3-0 lead through two periods. The goal scoring has been there as well for the Americans, who scored a total of 12 goals in the first two contests.
With a scoring attack that features the lethal abilities of Hilary Knight, Amanda Kessel and Brianna Decker, Team USA looks nearly unstoppable. But against a staunch defense in the Canadians, goals will be at a premium.
Who ya got?
Canadian goalie Charline Labonte knows the severity of the game and told Allen, "We're so passionate, this is our Stanley Cup, so I think we leave our emotions on the ice."
Both teams clearly want it, but this game might not be as important as one looming down the road.
The two teams are simply competing for placement into the next round of competition. But with the history of both programs, there is no doubt they will meet again for the gold medal on Feb. 20.
So consider this game similar to a preseason matchup in the NFL. And just remember, the Seattle Seahawks and Denver Broncos met before the season started. When these two teams meet, it will be much like the Super Bowl for women's hockey.
