According to reports and eyewitness accounts from fans, EXO's Lay lost consciousness at Incheon Airport while waiting for a flight.
On October 11, Lay arrived at Incheon Airport to catch a flight to Japan for EXO's upcoming solo concerts. However, the singer suddenly fainted right before boarding his flight and was quickly transferred to hospital. It has been reported that the rest of EXO cancelled their flights to watch over Lay.
Shortly after Lay's collapse, SM Entertainment released an update on the situation and stated that "Lay momentarily fainted due to a lack of sleep. According to the doctor, he will be fine after getting plenty of rest. Lay will be returning to the dorm in order to get some rest. He has stated that he wants to join the concert, but we (SM) will decide after monitoring his situation."
As for the rest of EXO, the group rescheduled their flights to Japan and it appears the the concerts are going on as planned. According to Kai on a recent V LIVE broadcast, Lay says he is "alright and not to worry too much" and that he "will be flying to Japan tomorrow [October 12]" for EXO's concerts.
Hopefully you're feeling better, Lay. Rest up before you return to the stage!
