Honduras scored the biggest upset of the 2012 London Olympics by beating Spain by a 1-0 score on Sunday in a pivotal Group D matchup.
Luis Fernando Suarez's club got to Spain early and was able to hold on for the final 80-plus minutes to ensure that the Spaniards won't be heading to the knockout round.
The Hondurans weren't the only squad that scored upsets over teams that were heavily favored to not only win the match, but press on to the latter stages of the Olympic soccer competition.
These unexpected victories not only seriously impacted the outcome of the teams involved, but contributed to shape the landscape of this entire competition.
Surely, you missed some of the results, so we'll help you out with that.
Here is Honduras and three other sides that shocked favored teams.
Honduras 1, Spain 0
This was about as close of a David vs. Goliath match that was to be showcased at the 2012 London Olympics.
Spain boasted one of the most formidable rosters in the entire competition. The likes of Juana Mata, Jordi Alba and Iker Muniain were supposed to run roughshod on Group D and easily secure an appearance in the knockout stages.
However, MLS players Jerry Bengtson and Roger Espinoza teamed up to dominate the Spaniards at the beginning of the match. Espinoza sent a cross to the middle of the box that Bengston headed past the goalkeeper for a seventh-minute tally that withstood a furious onslaught from Spain.
La Roja had countless chances in the latter half of the final 45 minutes, but could find the back of the net despite numerous golden opportunities.
The result guarantees that Spain heads home empty-handed and Honduras needs just a tie in its final group match to advance.
Japan 1, Spain 0
In the opening match between the two favorites in Group D, the Japanese shocked the Spanish even more so than Honduras.
We all expected Spain to start the competition off on the right foot in the form of a whooping at the expense of Japan, but instead, we saw one of the best teams in the entire world lose by a one-goal margin.
This matchup marked the first time that we saw a Spanish club stray from the patented "tiki-taka" style of play in quite some. We know that it was the U-23 team, but the players on the field in this matchup were the players of Spain's future.
In a shocking occurrence, Japan is tied with Brazil for the most points among the 16 teams competing in London. The Japanese are moving on, there's no way around that, but the upcoming match against Honduras will determine what place they move on in.
Senegal 2, Uruguay 0
Uruguay was one of the favorites to advance from Group A, even more so than Great Britain. However, all of that changed when Senegal pummeled Uruguay despite playing much of the match a man down.
Moussa Konate got the scoring started for Senegal, breaking the scoreless tie 10 minutes into Sunday's match. Konate scored the second goal for his team as well, using his head to pad his team's lead.
When comparing the soccer history of these two nations, it would be foolish to pick Senegal to beat Uruguay, but that's why they play the game.
Luis Suarez and company failed to get the job done for Uruguay and now find themselves in a must-win situation against hometown favorite Great Britain on Wednesday.
