Kramer made his first appearance of the tournament in Germany's round of 16 match against Algeria as a 109th-minute substitute for Bastian Schweinsteiger. He started the 2014 FIFA World Cup Final, due to an injury to Sami Khedira minutes before kick off. Kramer, however, was forced to leave the game in the first half after taking a hit to the head, and André Schürrle came on to replace him. It was later revealed that Kramer may have suffered a concussion from his collision with Argentine centre-back Ezequiel Garay. Referee Nicola Rizzoli admitted that 14 minutes after the collision, Kramer came to him, asking if the match was the final. Rizzoli then informed Schweinsteiger and Kramer was substituted off. The incident was later satirized by his national teammates Thomas Müller, Manuel Neuer and retired national team captain Philipp Lahm in a video which was shown during Kramer's appearance on the German sports show "Das aktuelle sportstudio".
