Immediately after the injury, Yeon Jung Hoon visited the hospital, but due to his personal wishes to continue with the filming, he wrapped up the recording with the cast and then followed up with treatment for his hand."

The label continued, "He received a minor surgery and is now recovering. The injury is not severe, so it will not affect any future recordings for '1 Night, 2 Days'."
