A teenage soccer player in Brazil was DECKED by a flying karate kick during an insane brawl in a championship game ... and the dude came away from the scrap with a gnarly wound.
The wild scene all went down Monday in Curitiba, Brazil, where Fluminense and Athletico Paranaense were duking it out for the U-17 Brasileirão title.
In the 93rd minute of a tight game ... Fluminense's João Neto was charging for a ball looking to add on to his team's scoring sheet.
The problem? He was tackled around midfield, and was so pissed about it, he came up shoving.
