At night on December 25, SM Entertainment released a statement about Red Velvet’s future activities through their official fan café.

During rehearsals for the SBS Gayo Daejeon earlier that day, Wendy fell off the stage and sustained injuries to her face and fractures on her right side. As a result, Red Velvet did not appear during the live show of the SBS Gayo Daejeon, although their performance of “Psycho” was aired.

According to SM, individual Red Velvet members will participate in the pre-recording on December 26 for their planned collaboration performances for the KBS Song Festival. They will not be recording their group performance at this time.

The 2019 KBS Song Festival is scheduled for December 27.
