A teenager is reportedly in a coma after falling off a skateboard whilst filming himself for an appearance on Anderson Cooper’s new show.

A producer for the daytime programme “Anderson” allegedly encouraged the boy to record his wild behavior for a show on the teenage mind.

Anderson Cooper, who has only been hosting the show for three weeks, is “very saddened” by the incident and is praying for the boy and his family.

A representative for Anderson Cooper said producers had been working with the boy and his parents on the science behind the teenage brain.

“As part of our routine process, we ask guests for video footage and photos,” he told Gawker.

“We did not provide the family with a camera.”

On the morning the boy was supposed to travel to New York City, producers found out that he had been injured.

The teenager was encouraged by Anderson Cooper’s new show producer to “film the crazy stuff you do”, but suffered a severe head injury when falling from his skateboard, a source told Gawker.

This left the teenager in a coma and the show never aired.

“I was very saddened to hear the news of this accident, and want to express my deepest concerns for the teenager who was injured,” Anderson Cooper told Gawker through a spokesman.

Anderson Cooper added that his “thoughts and prayers” are with the boy and his family.

Emmy-award winner Anderson Cooper is a Yale University graduate and joined CNN almost 10 years ago after working for ABC and Channel One News.
