Is Intak sick or injured? (1 Viewer)

Genuine question.
I was so hyped to watch them perform JUMP live
but Intak just randomly appears through out the choreo.
He's only there for about a couple of seconds at a time.
They rest of the time it's the other 5 members on stage without him.
BUT he's moving like he isn't injured and he is fine.
Why is he barely in the choreo!?!??!​

Google gave me this as the first option, could be that and him being careful. So maybe he can move okay for now/good enough to not have it be noticeable but want to prevent it from getting worse
