EXO's Kai and Tao have concerned fans by being absent from the group's performance of "Growl" during their 2nd 'EXO'luXion' concert in Seoul.
According to reports, Kai fell under the stage when a hatch for a lift opened suddenly under his feet as he was about to go on. Fans then noticed he wasn't present on stage during "Growl" and were concerned for his safety.
Tao also missed the group's performance of "Growl" which only helped to fuel recent rumours that he might have been taken to hospital for an injury.
SM Entertainment are yet to confirm that the pair are both unhurt. Hopefully they are!
