'Real Men's PD Kim Min Jong told OSEN on September 25, "Park Gun Hyung has been diagnosed with a disc injury in his neck and is adjusting his schedule with his agency. There is a high possibility that he will not take part in the filming scheduled to take place after the new-recruit special."

The PD also confirmed that the actor was not injured while filming 'Real Men', stating, "During the filming of 'Real Men' earlier this month, Park Gun Hyung took on [military] training without any issues."

His agency Namoo Actors stated, "Park Gun Hyung, who was awaiting his encore performance of the musical 'Hedwig' in October, was recently diagnosed with a disc injury in his neck and was advised to rest... It will be difficult for him to take on [the encore] performance of 'Hedwig', and we are reviewing his schedule for 'Real Men'."

However, you can still catch 'Henry's dad' on 'Real Men' this Sunday. We wish Park Gun Hyung a safe and speedy recovery!
