Why is Aditya being called wildcard?

Aditya was only out due to being hurt. How is that a wildcard entry? He wasn't eliminated.

I was wondering too.We most of the people were convinced that he was retired hurt but he was not eliminated.So i was confused too seeing him as a wildcard.May be that is show's format that if someone stays away from couple of tasks he is considered as eliminated.I don't know.

Putely caz othets refused to comeback maybe

I have been saying this that adi is retired hurt but not a wild card.Why he is called wild card,only makers know.

That question also pop up in my mind and i am still clueless

That is also a question to me
