"I don't know anything at all about the first half. I thought later that I left the game immediately after the tackle. I have no idea how I got to the changing rooms. I don't know anything else. In my head, the game starts from the second half."
The blow to Kramer on Sunday is one of several scary head injuries that occurred during the World Cup.
