SM Entertainment let fans know that Sulli was unable to film with f(x) for 'Music Bank' due to a bad cold.
Only four f(x) members performed "Red Light" on yesterday's 'M! Countdown' where the group took the #1 trophy, and fans were worried after seeing Sulli was missing once again on the 'Music Bank' stage. It appears that Sulli's condition worsened after this week's recording of 'Show Champion', and she won't be promoting on music shows for the time being.
SM Entertainment stated on July 18, "Due to a cold and body aches, Sulli didn't feel well and wasn't able to participate in the 'Music Bank' filming. It's been decided that she will return to promote on shows only after she recovers."
Get well soon, Sulli!
