After he missed a safety net during an "human cannonball stunt", a circus acrobat sustained potentially life-threatening injuries.
According to Gwent Police, the 28-year old man was taken from an event in Llanbradach (Caerphilly) at 18:15 BST on June 29th.
The performer is seen on phone footage falling into a barrier made of metal.
Uncle Sam's American Circus stated that he would "make full recovery over the course of time."
Footage showed the man being shot from a cannon and then crashing into a perimeter metal rail.
Cherokee Jones, an audience member, said that "he was out cold on floor."
"The show entered an early interval, stating that they needed medical attention."
Footage captured him lying motionless on a floor while a colleague from the circus ran over to assist.
"They placed the guy on a mat and took him behind stage. There was no sign of him awake," Ms Jones stated.
"The ambulance arrived in about 10 minutes, and they were driving on to [Llanbradach Showfield] by then the show was back up."
According to circus bosses, the performer was one in six "daredevil" human cannonballs who attempted "such a dangerous feat".
Caerphilly council has been notified and the Health Safety Executive has been informed.
The council stated that it was aware of the incident, and was conducting an investigation.
