Last summer in July, EXO started a new concert tour 'EXO Planet #3 - The EXO'rDIUM'. The group successfully completed performances in Manila, Phillippines last month and they're scheduled to continue on the tour in other countries. 

However, Lay will not be able to attend the remaining concerts. On March 10 (KST), event management company Dream Maker Entertainment Limited made an official announcement regarding Lay's absence.

The announcement stated, "Lay will not be able to attend the oversea tour scheduled in the future due to his failure in schedule adjustment. It's unfortunate that we have to deliver such news to everyone who's looking forward to Lay's attendance at Kuala Lumpur, Singapore, and North America. The remaining tour will be completed with the 8 members without Lay."
