Christoph Kramer replaced an injured Sami Khedira for Germany. His match did not last long. He took a blow to the head and tried to play on. He was subbed off in the 31st minute in obvious difficulty. Shades of Javier Mascherano in the World Cup semifinal and Alvaro Pereira against England.
No player wants to get subbed out of the World Cup Final. But, with what we know about head injuries, it’s time for FIFA to have mandatory neutral evaluations and free substitutions for concussions.
