He will be ok.
It was reported that during last nights performance of EXO at the 2013 MAMAs, Member D.O was injured. After the performance he complained of his ankle causing problems. He was then taken to a local hospital in Hong Kong where he was treated. It was found that there was no injury to the bone, and once he returns to Korea, he will receive physical therapy to fix said injury.
Due to his injury however, D.O was not present when the group received their Album of the Year Award, but I’m sure he had his own mini party when he found out the good news. The group performed Growl and Wolf, which were both very long and extraneous.
