Yes you heard right, Jungkook has injured his leg after flying stunt.
"After the 2016 Mnet Asian Music Awards had ended, fans were eagerly waiting to say goodbye to BTS as they departed Hong Kong," when they realized Jungkook couldn't walk on his own. It's believed during his flying stunt he hurt his leg and his waist, but still continued to perform in his condition.
All we can do is stay strong and hope his injuries aren't as bad as they seem! Get better Jungkook! The ARMY loves you!
I saw this information first on a BTS fan page and researched to confirm that it was real. If you'd like to look up the Facebook page it's BTS - 방탄소년단 Where I found the new report http://www.koreaboo.com/news/bts-jungkook-injures-leg-after-alleged-flying-stunt-accident/
