The Russian team has been cut from the invited players, cleared by the IOC to play. While Russia is questioning some players left off that invite list — which should not be seen as the same as a ban, they haven’t been — they’ve also released a roster for the men’s tournament, with the women’s to come later today.
My speculation on the list of players Russia wanted, but are not allowed to come is that they were out of Russia, and out of doping control for some period of time, and it’s a lack of clean tests, not a lack of tests that were clean that’s at issue in many cases.
