Coco Gauff is out
Also, in cycling, one of the top Colombians, Dani Martinez, is out due to lingering COVID. Colombia is still probably the strongest team from the Americas, but the aren't bringing Martinez or their top guy, Egan Bernal. Team size varies based on rankings in the world, so Colombia qualified for 5 but is now down to 4 cyclists, Canada gets 3, and the USA gets 2 for the men's road race. For the women's race, the USA is one of the top countries, so they get 4 cyclists (max for the women's teams).
