After various speculation about filming dates, MBC's 'Idol Star Athletics Championship (ISAC)' has released a statement.
A rep from MBC revealed on September 4, "'Idol Star Athletics Championship' recording schedule has been canceled. However, the program itself has been tentatively delayed."
Due to the ongoing MBC strike, MBC had previously stated that they were recruiting a replacement PD, after Heo Hang PD's resignation and that they would outsource the staff members. They also stated that the recording for 'ISAC' would take place on September 4 and September 11.
