Uruguy midfielder Alvaro Pereira took a brutal knee to the head during Thursday’s match against England. Pereira went for a slide tackle on England’s Raheem Sterling and Sterling ended up inadvertently kneeing him in the temple.
For a moment, it appeared that Pereira was knocked unconscious by the blow. He was somehow able to walk off under his own power and hardly missed any time. The scene was scary at first.

Like the NFL, FIFA has been trying to pay closer attention to head injuries. I’m not sure how Pereira was not required to pass some sort of concussion protocol before coming back into the game, especially when you look at the way he was walking off the pitch.

Hopefully Pereira didn’t suffer any type of serious injury. That looked really bad.
