United States badminton player Beiwen Zhang was forced to retire from her match on Thursday due to an apparent Achilles injury. She was the last U.S. badminton player left in the 16-player field.

The U.S. athlete had been playing well; she led the match 1-0, after claiming the first game by a score of 21-14, and was trailing just 9-7 in the second game to China's He Bing Jiao.

Zhang was brought to tears after the awkward landing, and she was eventually taken off the court on a wheelchair for further evaluation. Though she was forced to forfeit the remainder of the match, allowing Jiao to advance to the quarterfinals, Zhang never lost a game in the 2020 Tokyo Olympic Games. She defeated both Ukraine's Maria Ultina and Brazil's Fabiana Silva by a final score of 2-0.
