SHINee's Onew was unable to join fellow SHINee members on stage for the KBS "Music Bank in Paris" world tour concert due to his ankle injury.

At the press conference of the concert, fellow SHINee member Jonghyun broke the news and apologized to the fans saying, "Onew's ankle got injured so he cant stand on stage. Were sad and disappointed he cant join us today. Hopefully in our next performance in Europe all five of us will stand on stage".

Also, this is SHINee's second time in Paris as they performed in Paris last time for SMTOWN in Paris concert. Jonghyun said that they will try their best to show a very good performance for the concert and also this opportunity is a good way to interchange cultures between the two countries.
