In the round of 16 in the 53-kilo class, Sofia Mattsson lost to Vinesh Vinesh.
The Indian with the same first and last name clearly won 7-1.
Mattsson, who took Olympic bronze in Rio de Janeiro in 2016, can still leave his fourth Olympic game with the same value.
She can go to the bronze match via relegation.
Who she will face in the first rematch match is unclear.
