Belgium may have already qualified for the round of 16 of the 2014 World Cup coming into their tie with South Korea, but their chances of ending the group stages with the maximum amount of points took a significant hit following Steven Defour's red card just before half-time.
The Porto midfielder went into a challenge with his studs up and hit Kim Shinwook in the shin (no pun intended), giving the official no choice but to hand the Belgian his marching orders.
Football Vines shared the moment of the challenge:
Defour had been playing a very solid match up until that point, as shared by Squawka:
The reaction to his poor challenge was one of disbelief, as the first half hadn't been a particularly rough one. Bleacher Report's Karl Matchett didn't want to hear any Luis Suarez comparisons:
The Belgian Waffle was curious how this would impact the second half:
Paddy Power had no problems with the straight red:
Defour made history with his challenge in the worst possible way, per OptaJean:
Graham Ruthven was impressed the official actually caught the severity of the incident without the use of instant replay:
This particular fan explained to the world this was good for the Korean team:
Defour only made his first start of the tournament against South Korea, as Belgium chose to field a starting XI comprised mostly from squad players to avoid injury or suspensions for their stars going into the round of 16.
The Red Devils will most likely meet the USA there, and while the Yanks aren't exactly a football powerhouse, they will challenge a Belgian side that has under-performed so far in the tournament.
South Korea need to beat Belgium in order to have any chance at progressing, and that task just became a little easier thanks to Defour's inexcusable action. They'll still need some help from Algeria, however, as Russia would go through with a win against the Desert Warriors thanks to a superior goal difference.
