## Uncertain athletes

The next 197 athletes have an uncertain status: they have not participated at one (or more) of two or more sports but their appearance in the Olympic official website is considered official. Some of them have been already included in the list above. There are also some contrasts between Olympedia and the Olympics official website regarding the number of appearances.
Sports in italics are those sports that are considered as official in the Olympics website or Olympedia but the athletes have not participated at them (or one out of more times: in these cases the number written is the number of the Olympic appearances in that sport including the uncertain and in the notes is written only the total of the official appearances).
The total Olympic appearances contains the uncertain Olympic appearances too but not the 1906 Intercalated Games.
The most common combinations of uncertain sports are swimming/water polo (73), athletics/gymnastics (21) and fencing/modern pentathlon (13).
