Scary stuff right there. Apparently the player struck by the goalie’s knee began to swallow his tongue. The opposing team defender reacted instantly and was able to get the young guy breathing again. I know people like to knock soccer players for diving and prancing around like little girls at times, but this incident proves how dangerous the sport can be. There was little to no intent by the keeper; he was simply protecting himself, and this guy ended up catching it hard. Kudos to all the players and personnel who responded instantly in helping this young man regain consciousness.
P.S. Yikes.
