During the Road FC 39 mixed martial arts event in Seoul, South Korea, one fight has been put to an end instantly for an unlucky and ultimately painful reason.

The unfortunate incident happened during the super-heavyweight faced off between Aori Lee and Hyun Man Myung.

In the first few seconds of the opening round, Hyun Man Myung struck his opponent with a devastating low blow that left Lee in agonizing pain.

The fight was immediately called off after Hyun Man Myung’s low strike seems to ruptured Aori’s testicles.

Watch the painful moment:

Being hit in the groin is every man’s nightmare. This could be the worst low blow in MMA history.
