You can immediately consider Russia out from team sports in which they qualified, so volleyball, 3x3 basketball and probably beach volleyball, because they represent "Russia" (probably, however, beach volley could be an exception). Also, they will be out from Olympic Qualification Tournaments, so I guess also women's basketball and men's basketball. Things are different for sports such as gymnastics, archery or rowing, for example, in which some individual competition exists and some legal ways to take part to Olympic Games may be found
