Tournament favourites USA lost 3-0 to Sweden in their opening group game at the Tokyo Olympics.
The number one ranked team in the world were unbeaten since 2019 but it's not the first time they have tasted defeat at the Olympics against Sweden, who also got the better of them in the quarter-finals in 2016.
Seven out of 11 starters from that game in Rio started for the United States on Wednesday but the world champions were stunned by the Swedes.
Striker Stina Blackstenius scored a goal in each half for Sweden and any chance of a fightback from the USA were dashed 20 minutes from time when substitute Lina Hurtig added a third.
The USA - previously unbeaten in 44 games - were able to include the likes of Alex Morgan, Rose Lavelle, Sam Mewis, Tobin Heath and Lindsey Horan in their starting 11 and not even the introduction of Megan Rapinoe or Carli Lloyd could spark a comeback.
