This is the hilarious moment a girl collapsed clutching her back after being hit by a ball, only to be struck again moments later by a second wayward shot.

Dramatic CCTV footage shows the female hostess in a white dress arranging the balls in the rack when the cue ball, played on a nearby table, bounced off and hit her back in Jiangsu, China.

The item struck the woman directly, causing a man playing at another pool to rush over and help her stand as she cradled her back in pain.

Seconds later, another cue ball shot off a table and smashed into the worker's head.

The woman winced and eventually sat down on the ground while another man quickly approached to check if she was injured.

Meanwhile, other players and bystanders watched the scene with surprise and concern.

Local media reported that the rack attendant did not sustain any serious injuries from the incident.
