Yeah, you have to make the finals, or take 3rd, I believe.So if there's a true 3rd for the last spot,then you don't qualify just by making the semis right? You would have to either make the finals, or win bronze plus win the true 3rd match
Sayeth UWW:
...Apart from the 36 finalists across three styles, the bronze medal winners will also have a chance to get a quota for their country. An additional wrestle-off will be held between the two bronze medal winners and the wrestler who wins the quota wrestle-off will take the trip to Paris.
