The United States Soccer Federation condemned the online racist abuse directed at several players after their 2-1 defeat by Panama at the Copa America.
Monaco striker Folarin Balogun, Crystal Palace defender Chris Richards, and Juventus players Timothy Weah and Weston McKennie were targeted online after the Group C match in Atlanta.
Weah, 24, received a red card in the 18th minute for punching Panama's Roderick Miller. He apologized, calling it a "moment of frustration."
US Soccer stated on X: "There is absolutely no place in the game for such hateful and discriminatory behavior. These actions are unacceptable and contrary to our values of respect and inclusivity."
Despite being down a player, the US took the lead with a superb strike from Balogun, his fifth goal in 14 appearances. Panama equalized four minutes later with a goal from Cesar Blackman.
The US defended well but conceded a late goal to Jose Fajardo. Panama's Adalberto Carrasquilla was then shown a red card for a reckless foul on Christian Pulisic.
Co-hosting the 2026 World Cup with Canada and Mexico, the US is now level on points with Panama. They need to match Panama's result against Bolivia in their final group match against Uruguay on 2 July to advance to the last 16.
