RIO DE JANEIRO, Brazil -- Germany midfielder Christoph Kramers head injury in the World Cup final on Sunday has revived concerns about the way football deals with concussions. What is the best place to buy knockoff jerseys . It was the latest in a series of head injuries at the World Cup that raised questions about the sideline medical checks. Kramer continued playing for 14 minutes in the first half of the final at Maracana Stadium after taking a heavy blow to the face in a collision with Argentina defender Ezequiel Garay. He was eventually replaced in the 31st minute after slumping to the ground, and the German football federation said he had a suspected concussion. It didnt give any more details. Kramer appeared to be disorientated as he was helped off the field by medical staff. In his absence, Germany went on to beat Argentina 1-0 in extra time to lift the World Cup. "I cant remember very much but it doesnt matter now," he said, shrugging off the injury. "I have to send regards to my grandmother. She has a birthday today and I couldnt reach her." There were worrying head injuries for players earlier in the tournament. Argentina players Javier Mascherano and Pablo Zabaleta also played on in their teams semifinal against the Netherlands in Sao Paulo after hard knocks to the head. Mascherano appeared to be completely disorientated and fell to the ground after a clash of heads with a Dutch player. Both Mascherano and Zabaleta started in the final. Questions about FIFAs concussion protocol were initially raised in the group stage of the World Cup when Uruguay defender Alvaro Pereira refused to leave the field after being hit in the head by an England opponents knee. Pereira lay motionless for a short while and appeared to be briefly unconscious, but was still allowed to come back onto the field and continue playing. Uruguay team doctor Alberto Pan initially made hand signals for a substitution but then seemingly changed his mind after the clearly dizzy player furiously protested. The images provoked criticism from professional players union FIFPro, head injury specialists and others. Pereira later said the blow knocked him out and "was like the lights went out." "I was also not happy with that situation. I must confess that," said Michel DHooghe, a member of the FIFA executive board and chairman of its medical committee. The incidents have led to debate over whether FIFA should allow a temporary substitution so a player can get a head injury properly checked. Top-level rugby, for example, allows players who are suspected of having concussion to leave the field and be looked over by a doctor, and temporarily replaced with someone off the bench. FIFA medical chief DHooghe told The AP earlier in the tournament that he doesnt oppose the idea. What is the best place to buy Cheap Jerseys .
