Justin Bieber, 16, was scheduled to perform on the German variety show "Wetten, dass…?" (Wanna Bet?), but canceled his performance when a stuntman, whose act was before Bieber's, was critically injured. The accident happened in front of a live studio audience and more than 8 million TV viewers.
Samuel Koch, 23, suffered serious back and spinal injuries when his stunt went awry–he didn't completely clear a car he was trying to jump over using spring-powered stilt shoes.
After the accident the rest of the show was canceled, and Bieber asked his fans to keep Koch in their thoughts: "we all don't think it is right to continue. Please pray for Samuel Koch & his family as we wait and hope for his health and safety."
Bieber later apologized to Germany for the unexpected cancelation. "Germany I'm sorry we couldn't perform tonight but some things are more important than putting on a show. We will be back I promise. Thank u."
After Koch had surgery on Sunday, he was put into an artificial coma. A German doctor said he was "in an extremely critical stage", according to a German newspaper. This is the first very serious injury for "Wetten, dass…?", which has been on the air for 29 years.
